Sokoban is a series of puzzles involving pushing but not pulling sacks into certain positions on a grid field. There are several programs available.

Not very practical but pretty neat. Filipponi's MacPipes pressures you to make the longest continuous pipe you can using the pieces provided. Carl Limsico's Short Circuit is a unique puzzle where similar objects can be canceled only when there is an unobstructed path between them.
