Give me rock hard(ish) abs!

I started following hundredpushups.com today. I'd like an exercise plan along those lines to follow on the off days to work my abs. Is there a hundredsit-ups-type plan? Are sit-ups even the best way to strengthen my abs? I'm only looking for exercises that I can do at home without equipment and without much space.
