Queen v. knight

A left mouse click will place a Knight; a right mouse click will place a Queen. The object of the game is to place the 4 Queens and 4 Knights in positions that do not threaten each other. If that bores you then you can just try placing 8 Queens on the board without them attacking each other (the 8 Queens Problem). from Javaboutique

If you do solve it, type your name in the box and print out.
