Rollerscape from ThinkGeek lets you “design and build a desktop roller coaster using the included construction pieces — snap on the tracks wherever you like, and then begin the testing phase by taking one of the included marbles for a joy ride.” Video after the break.

If at some point in your life you never dreamt of designing roller coasters, then you must be an acrophobe. If you are an acrophobe, then we have the perfect toy for you. If you aren’t an acrophobe, and don’t currently design roller coasters for cash, then we also have the perfect toy for you. Rollerscape
