I used the Stamps (see Gifts on this Web site) as a lighting control box on a lark recently, to light a friend's alternative rock band—my lovely 3500 lumen, 1400 x 1040 Canon Realis SX 6 was the whole lighting kit. People liked the lines, and I admit they moved well and seemet to support the music, but they just weren't doing the job as sources of light for the band. So I took the next two days and wrote a lighting program. Apples and Arrows, a friend's band: LiveLighting's first night out. There are more clips at my YouTube page. I'll likely release it as another gift at some point, but it needs some tidying up before I do. Happily, the interface seems straightforward enough: an interested bystander asked how it worked and I handed him the stylus for my Toshiba M 400. Training took three sentences and he took over for two songs. Here's an applet version to play with. Most of it works like (I hope) you might expect, but I'm particularly happy with how you can move a recorded motion to follow moving performers: just drag the recording widget. That also got around the issue of naming a recorded action in a performance situation: here, you just drag the widget close to what you're recording: no label needed! (Patent pending, but if you're coding not-for-profit or personal work, e-mail & I'll happily grant a license to the concept gratis.)
