Steve Wozniak winds down Wheels of Zeus, GPS-like tracking system: The company, founded by Apple co-founder "Woz," had as one of its early project ideas that of providing an inexpensive method of tracking children using widely spaced transceivers and low-power RFID tags that might be cheap enough to be sewn into clothing and backpacks. The transceivers could be mounted in public places but would also have been in individual homes. The plan to deploy this network was never made clear. The company is winding down as Woz and two former Apple executives move into a shell firm that's looking to spend tens of millions of dollars to acquire and incubate tech firms. (The name: Acquicor, which was probably not the result of an expensive name search.)
