I love TwixT, I discovered the Bookshelf Games version of this recently (a friend of mine's parents had an old copy at their beach house). Also a big fan of Alex Randolph's Ricochet Robots.

Dieter Stein's games are also supposed to be wonderful abstracts (Urbino, Fendo, Tintas) though I haven't had a chance to play those yet.
