Still thinking about changing my final project idea: interactive plant vs blinky lights?

A discussion Monday night got me thinking about my Phys comp final again. I like the bionic gardening, but I also want something really fun. The other student I was talking with was trying to convince me to do my original-ish LED light board idea. So, at home I thought about it a little bit more.

If I had the time to do this, I’d get 108 RGB LEDs, and a perfboard in 5″ x 5″ squares to measure a rectangle 30″ L x 10″ H. Each LED would be spaced 2.5″ from its neighbor, so that there would be 9 LEDs per square.

The interaction: When a user walks by, the LEDs light up in response. The color of the LED depends on how far or close the user is to the LED board. So, the closer, the more red; basically it goes through the visible light spectrum starting from indigo to red.

In addition, my original idea had sound output as well. Sound might be too confusing. I sort of just like the LEDs. I think this is something that would look spectacular, but I just don’t feel that I have enough time.

UPDATE: Perhaps I’ll just do this on my own, anyway. Seems easier than the UV Sunlight watch, but more difficult than the talking plant. In any case, I need to order ton 0′ parts, soon!
