Build a magic ball and make all wishful leaning more meaningful as you steer it down the lane with your body.

There are probably a number of things one could use for balls, but is using large ball bearings. The lane is nearly six feet long, so this is more like medium-format bowling or maybe even skee-bowling. An Arduino Uno keeps track of of the frame, ball number, and score, and displays it on an LCD. Whenever a pin is knocked out of its countersunk hole, the LED underneath is exposed and shines its light on a corresponding light-dependent resistor positioned overhead. Those glowing pins aren’t just for looks - the LEDs underneath them are part of the scoring system. But why pay all that money to don used shoes and drink watered-down beer? Just build a tabletop bowling alley in your spare time and you can bowl barefoot if you want. Bowling has been around since ancient Egypt and continues to entertain people of all ages, especially once they roll out the fog machine and hit the blacklights.
