A little idea utilizing a new level of indirection. You might call it "HoloTile meets Segway". A platform is one square meter (or rather circle) capable of moving in any direction (using conventional wheels). It is covered with HoloTile. A person on it just "walks" on it in any direction and the soft/engine just moves him or her in this direction, but much faster. Probably some self-balancing magic is needed in order to keep the person standing firmly
