After a bit of work over Thanksgiving break, I was able to get the laser projecting Asteroids well enough to play. I apologize for the quality of the photos, but we were really interested in large projection, so the beam was dim and my camera didn't capture it especially well.
I was happy to see a number of ACM folk braved the extreme cold weather to play Asteroids on exterior walls at the Krannert Center for the Performing Arts, an excellent venue which I intend on visiting again next Friday, when my good friend Erik will be playing Cello in the last orchestra concert of the semester.
This whole event turned out to be a quite a success with a Hot Cocoa + Helvetica reception afterwards, despite the fact that the software is still mostly a quick hack. I look forward to further development of additional laserware on the Mac.
Now just to write the real optimization code to make it work well... : )
