The arrows that led me through the Ikea store/maze weren't painted on the floor - they were projected using a small overhead projector the size of a camcorder. I've seen the spirograph lights at the rink and movie theater lobbies that use similar technology.
Of course, I thought of Figures and Moves patterns. There are some drawbacks (knowing how many lobes the skater intends to skate, not looking down, connecting the lobes) but it was an intriguing thought that kept my mind awake all the way to DC.
Have you ever seen something and thought "How can this be used for figure skating?"
(Backstory: I made Ikea one of my rest stops during my 9-hour commute last week. Love their cafeteria and the bathrooms are always clean! It was pouring rain outside, so walking the Ikea Rat Maze was a good way to get some exercise after lunch before resuming my trip.)
