My brother Steve and I hand-cut and hand-painted 5,292 wooden dominoes plus some bigger-sized blocks after efforts to find large amounts of professional quality toppling dominoes fell short. This is the result of about $100 worth of materials and a whole lot of man-hours.We were happy with the outcome. We tried several new stunts and although one of them failed to trigger, the course never needed to be restarted.For close-up photos of key stunts and explanations on how they work, visit http://www.mazeguy.net/basement.htmlThanks for watching! :) Less
