Chess System Tal makes great ones.

It's something of a challenge to make them play credible ones, but it's fairly
easy to make them play stupid ones.

For instance, if you start adding opposite castling king terms, you'll start
sacrificing your h-pawn even when it makes no sense, for instance when there are
no rooks on the board.

I still think that CST's are the most creative.  Some of the games Thorsten has
posted have featured sacrifices that are creative even by human standards, in my
opinion.  Most computer sacrifices seem very wooden compared to these.
