Question: What toys do you like playing with?

I recently helped my daughter make a model of a ballista (an ancient seige weapon that threw large rocks at castles). It was very small but easily threw maltesers across the room. At work the coordinate measuring machine [myimage1] is both fun and infuriating. It is a big, accurate ruler that works in 3 dimensions.
