Flügelrad

When two players turn the wheel, this can be quite constructive — at least if they play a game of Flügelrad.

The game board consists of seven hexagonal spaces, each of which has a hole in its center for the impeller wheel. The game is played with marbles; each player has their own color. On your turn, you reposition the impeller wheel, then rotate it as far as you like, thus moving up to six marbles at the same time.

The first player to form a contiguous cluster of at least six of their marbles wins. But beware since you can easily move your opponent's marbles as well...
