So, again, killing time on Andrew's blog, and I found a link to Instant Music Video and went to this IKEA link. All I can say is, I heart IKEA. You can pick a room, play music, and watch the characters twirl. OR, as my super composer self discovered, you can also bang on the keyboard and create your own percussion tracks AND you can even upload a piece of yours.
Which I did. It's probably best to upload something of yours with drastic subito dynamic markings.
For my viewing public to see, I taped this with my digital camera (who knows how to tape what is being played on your computer in real time?). Hey, I can't afford Michel Gondry, but they can. Enjoy!
