Discovered Duff's device the other day. Wow. I didn't even know you could do this in C. Took me a good 10 minutes to even figure out what he's doing, but the coolness and weirdness of this is even now still dawning on me. I wonder how many compilers can handle this properly...

The whole Lysator web site is an exercise in extreme coolness. Sometime when I'm not so roped in by work I really need to lose myself in it for a few hours.
