I searched and couldn't find this on the sift, so I don't think it's a dupe. This youtube video has the full length, but visit the original for better sound quality. I consider "old school flash" those videos that were popular on the internet before youtube-esque lossy-video-embedded-inside-flash became popular. Wasn't sure if I could embed the original though, so I just linked to this youtube video.

Here is the author's site, but geocities is slower than albinoblacksheep.

From the FAQ on his page:
"The statement at the end of the movie is absolutely true. The soundtrack was made entirely in Sound Recorder. But that may be misleading, since it took more that just sound recorder to make the movie.

Structurally, the sound track is made of short clips of noises or combinations of noises. Each of these clips was made in sound recorder by distorting one of the four sounds used: ding, chord, chimes, and the Mircosoft sound.

Then sound recorder was used to mix each of these clips together into one synchronized file. Considering the amount of repetition in the song, this part was really quite easy.

Finally, the sound track was imported into Macromedia Flash, and used as the basis for the animation.

No, I didn't reprogram sound recorder to be able to play by itself. It is not a screen-captured movie of something that actually happenned on my computer. It is a fictional depiction of one way the soundtrack could have been generated (but wasnt).

The fake sound recorder windows were built out of pieces of screenshots of sound recorder, and then flash was used to animate their movement. I used mspaint (another of my favorite programs) to cut my screenshots up to get the pieces I needed."

This was absolutely awesome.

who needs music when you have techno?
