It’s (pocket-sized) blinkin’ flashin’ heaven.
One hundred and twenty-six LEDs, all on a space of about 3″ by 2″, all a-blinkin and a-flashin.
Of course the first thing I wanted to do was run Conway’s Game of Life on there. Turns out there was a GoL program already made, in the associated library / examples. Still, I had to tweak it a bit to get it to work ‘just so’.
Now all I gotta do is replace the Arduino with something smaller, maybe just the Atmega uC, add some batteries and put it in a little portable case.
Real electronics should glow in the dark.
