Hmm. If you really wanted it hovering, and had no compunctions about power bills, you could make it out of a light material, and have it on a fan base. However, If you got a stand that reaches around the top and the bottom, like a globe stand, 2 equally powered magnets would keep it in places. Say, one magnet on top, and one on the bottom of the oracle. They would both pull towards the top of the stand, and if they were of equal power, the would easily stay put. But, I'm not much of an expert, so its really up to you.
