I can't recall either, but that brings to mind an interesting project a
friend of mine worked on quite a few years ago. The Art Museum here was
having some kind of show and an artist wanted to paint electronic pictures.
My friend designed the electronics (I built the circuit boards) to put a
line of LEDs on a pendulum and paint pictures electronically as the pendulum
swung through its arc. With the multi-colored and higher intensity LEDs
available today, it would be really cool to do the same thing but with color
pictures. Doesn't sound like too hard a project especially with the speed of
todays computers.
