Control teams of multi - Lego Robotic platforms (made each of two standard Lego motors and some Lego plates and bricks - not included but available) manually from your PC keyboard or let your computer control them THROUGH WALLS (in the other room for example) while you are away from home (shopping, partying, etc)
Or control any other NON LEGO small DC motors with your computer - a motorized toy, some DC lamps remotely - think of all the things you could do for Halloween or Christmas or New Year's celebration.
Limited quantity. Get it while it's there.
