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.

LED lights for cars are also shatter proof and free from Mercury, making them much safer for home and the environment.

LEDs offer a potential energy savings and provide an eco friendly environment. LED lights are only the first and last choice in human lives.
