Occasionally when using the engineering item Gnomish Shrink Ray your character would be enlarged significantly. Even more interestingly, the effect stacked with other enlargement effects, which was disabled for most such items. Combining with a large based model (the tauren) and then riding a very large base model mount (rampaging yak item) I was able to make an immensely large yak for a few moments. The shrink ray also worked in arenas, which is also unusual. You'd have to give up a trinket slot to use it, putting you at a minor disadvantage, but on the other hand the startling change and intimidation can bring its own advantage.


I never got to try this but at the time I recall rogues having an ability that would let them copy the models of large entities like bosses. It stands to reason that if Blizzard forgot to consider the interactions of this item with others, rogues might be able to be even more ridiculously large.

CAD model for a simple holder/stand to insert your toothbrush that keeps it upright. Flared base keeps it stable under moderate tipping. Tapered hole made to fit a typical round toothbrush handle, though you may want to modify it to your particular brush brand. Easily 3D printed using the included STL file. Depending on the porosity of the 3D print, I recommend applying a coating of nail polish or some other substance to seal the surface and make it watertight to prevent mold growing inside the part.

A simple application for manually identifying chords and constructing chord progressions using the mouse. I wrote this program for myself as a way to bridge the gap between my basic music theory knowledge and my lack of ear training. Use this program to quickly construct the outline of a composition or song that you can then fill in with more detail later. You can check out the source code on github. Included is an executable for Windows, a rich soundfont to get you started, and a folder with some example chord progressions I made while testing the software.


HOW TO USE:


The program has two tables. The right table corresponds to a list of "all" chords containing the notes highlighted in the input column. Each row corresponds to a note and each column corresponds to a different chord. The input acts as a filter to narrow down the range of possible chords to look through. Highlighted cells are are the notes of the chord that will be played if you click the column heading, while cells with text in them that are not highlighted are also in the chord but will not be played. The articulation of the chord ("inversion") can be changed from the initial result by selecting or deselecting notes. The darker shade corresponds to the root of the chord.


The left table corresponds to a sequence of chords that can be added to by copying/pasting chords (e.g. from the right table). The sequence can then be saved to a text file (*.chord) and loaded later from the File menu.


Controls for both tables are similar:

  • LCLICK: Play a note or chord
  • RCLICK: Select/deselect a note, or delete a chord
  • SHIFT+LCLICK: Copy a chord
  • SHIFT+RCLICK: Paste a chord (into chord sequence or input column)
  • CTRL+SHIFT+RCLICK: Insert a chord into chord sequence


When you play a note or chord, the program uses the currently loaded soundfont to synthesize the sound. Notes played contiue to play until a new note or chord is played (or, if you "play" an empty cell to stop them). You can choose whether all notes in a chord are played simultaneously, or are played in an ascending/descending order with a small delay by moving the "Strum delay" slider. You can load a new soundfont with the "Load Soundfont" button, or choose a different instrument preset with the dropdown menu. The program comes with a default soundfont ("Timbres of Heaven" by Don Allen, http://midkar.com/soundfonts/ ) but you can find others to use. You can change the default startup values in the config.ini file (e.g. the soundfont loaded on startup, save path, and more).


An example use case:

  • Listen to a song whose chords you want to transcribe
  • Left click the input column to play various notes until you find one or more that seem to be in the chord, then highlight them to generate a list of possible chords
  • Left click the chord labels (at the top of the table) to play different chords and see if they match what you're looking for
  • Once you find the chord you want, shift-click to copy it and then paste it into the sequence table.
  • Repeat this process for the next chord, and so on.
  • Save your progress to a file to refrence it later.
  • Click on chords in succession from the sequence table to hear the progression you've built up.
  • Sing along, share the sequence, or reference the sequence as you create an arrangement.


Tips:

  • You can copy and paste to/from the input column. Chords pasted from the input column will be labelled as "?".
  • Playing chord(s) leading up to the current chord your are trying to identify is helpful.
  • You can do this by clicking in the sequence table.
  • Often the melody is easiest to identify and you may not be certain when a chord changes.
  • You can paste individual notes from the input column into the chord sequence and then reference them when figuring out the progression.
  • The leftmost column in the sequence table is there to provide note labels, but you can also highlight these cells to act as a reference e.g. for identifying what notes are in the key of the song.

My roommate pointed out that you could get interesting effects by pointing your webcam at your screen to create a feedback loop. I explored this a bit and got some pretty interesting results, especially as I began to understand what was happening and created a more controlled environment. The evolution is driven by the round-trip magnification, reorientation, gain, and point spread function. All of these vary slightly across the screen and lens and color channels, and can be adjusted by camera position, orientation, focus, and gain. If round-trip magnification is less than 1, you have a stuff moving from the edge of the screen towards a convergence point. If the magnification is greater than 1, you have signal (e.g. noise) from the convergence point propagating outward. If you get the magnification close to 1, then signals propagate very slowly and can even become persistent if the magnification varies with position due to the lens and screen. Very fun.


This third set of videos were generally at a magnification near 1, where signals only very slowly migrate in or out and can become fairly persistent.

This song is vaguely Enya-esque, written with the intent of being sung at my own wedding in 1989, but we were unable to get a flute player & I was too great a coward to sing outdoors a capella.... At any rate, I'm still as fond of the fellow I married as I was then...well, maybe a little moreso now....

This song was written after I attended the field memorial service of a young captain who was killed in a river crossing in Afghanistan in 2005. It is dedicated to all service members, especially those serving in our special forces, who have risen to higher standards of character and service in their campaign against human oppression worldwide. Many of us have known someone who has given life and/or freedom in what I consider the "greater" war, the war to preserve free choice, hope, and human kindness in a sometimes cruel world.


Inset into this song is a recording of the Special Forces Prayer, recorded by an SF chaplain. It is a moving reminder of how greatly we all rely upon our Creator in any good endeavor. I invite you to visit http://www.sfahq.org/the-origin-of-the-special-forces-prayer/ to read the origin of this prayer in detail. Briefly, I want to cite that the prayer was written by Army chaplain John Stevey in 1961 for the Green Berets about to ship out to Viet Nam. It has long been an inspiration to me, personally.


I hope you enjoy this reflection; it is what I witnessed and felt at the field memorial service --as much as can be captured in words, anyway. There's a kindred spirit that unites service members, particularly in times of loss. It can't truly be articulated, but it can give us the strength to live and give beyond ourselves for the sake of our brothers and sisters in service.


God bless the warriors who serve for hope of a better world!

This is another old one, dating back to 1980's, finally published in 2014 on the "For Love or For Honor" CD, although I don't believe it really fit in that collection. This one sounds vaguely Alan Parsons, as I was listening to a lot of his music back in that era. The song depicts Destruction as a living entity.

This one was inspired during my travel to Afghanistan, but also reflects my personal observation that a great many individual human experiences are profound and --in my belief-- not random. They change our character and shape our identity. I believe the spiritual universe, the unseen one, is behind many of these; for which purpose, when I have a solo experience that helps me grow or simply brings me joy (like rescuing that little bird yesterday, having the opportunity to hold it gently in my hands and take it to safety), I try to thank God for that event.

This song was a first-fruits offering, the title of my first CD and is dedicated to the younger of my two favorite (only) nieces and her awesome husband (Katelyn & Davis) for their courageous faith.

I also took "EverFree" as the pseudonym under which I publish out of respect for and gratitude to Yahushua (Jesus), who spent his brief ministry freeing the faithful from the burdens of man-made religion so that they could return to faith with hope. He also healed (freeing from affliction) and atoned (freeing penitent sinners from a death penalty). He freely and fully gave himself to all this, while living within the laws laid out in Torah --laws intended to teach people how to have good relationships with our Creator, parents, and one another. Yahushua is ever free!

My life experiences have taught me that the battlefield for the human soul is often the human mind; this is no doubt the adversary's intention when he aided human intellect to so far outpace human understanding.

I had the privilege to serve alongside some men "wearing funny little green hats" in Afghanistan. I began to realize that --far from being war-mongers!-- these guys took responsibility for improving fellow humans to a degree rarely witnessed. While I'd sincerely hate to be the bad guy around these folk, I found that being near them was a great experience as I tended to check my own character on a minute-by-minute basis.

I asked one of them one afternoon whether he was a Christian and he answered "I believe in God...." I tend to respect the honest doubter; truth is ever-so-much more important than dogma. I pondered that evening where my own faith would stand had I not had an unusually close relationship to my Creator as a child. The result was a desire to tell the story of Yahushua (Jesus) as a ballad about an exceptional spiritual warrior executing a hearts-and-minds campaign.

Sincere thanks to Leon of SOLO Creative Media for insisting that I add the second soprano (middle) vocal; it gave the ballad a nice retro flavor. I hope you enjoy!
