The WhirlyDome is a flurry of light and activity. Video games beep and hum in the arcade, and lasers ricochet in the laser-tag maze. The Dome’s core attraction, however, is WhirlyBall, billed as the world's only mechanized team sport. Players try to shoot wiffle balls into elevated goals as they steer bumper cars across the dome's two 4,000-square-foot courts. Dubbed WhirlyBugs, the electrically powered vehicles can reach speeds of up to 5 miles per hour, like turtles who are running really, really late.
