Steve Butterworth's snowmobile was a big hit. Last year it was the slot cars being raced by the public using InfraRed controllers, this year Steve has set up an ice rink with snowballs and everyone had great fun trying to get all the snowballs into the corners. Have a close look at the grey IR controller. You can see the LEDs that transmit the signal are placed right where your finger goes! I think this controller is from the crane outfit.
