One of the simpler yet more interesting toys we saw at the Toy Fair was the Wall Coaster, a customizable marble track that sticks to the wall. The Wall Coaster comes with 16 feet of track to create the ultimate marble run. It attaches to the wall using a non-marking removable poster putty making the tracks infinitely reconfigurable and allowing for creative play anywhere there’s a wall. It even comes with glow in the dark marbles. You can buy the Wall Coaster direct from the site or from Amazon for $19.95.
