You can buy even just 1 pv kits from many websites now.

charlieplex.

the attiny2313 has 18 i/o pins, but you don't really want to lose reset, so call it 17. you could charlieplex 272 leds on 17 pins, but you won't have enough memory. and sooner or later you'll have to throw in some transistors to sink the current from the leds. i've modified the code in the post to sink 8 leds at a time and it's still ok.
