what the lights spell when you glance
Mother's Day Gift
Inspired by an exhibit at the Boston Museum of Science, I made this desktop LED display for Mother's Day. A two dimensional image results if you sweep your eyes across the PIC 16C57 controlled one-dimensional array. It just sits there and flickers--until you glance away from it; then you see the message above: "I 'heart' MOM." After realizing that all three elements of the array are palendromes, I couldn't resist building it.
