Now this is something with potential for some fun. The "Mirage 3D Hologram Generator" is a precision optical instrument that claims to generate a perfect image and, as Newlaunches says, you don't need a Ph.D to work it. All you need to do is place an object in the small bowl, and what appears to be a detailed replica will hover over it.
We're a bit wary of passing along anything sold through a site with a name like "Eyetricks.com," but it insists that the $36 device has been used in schools and universities to teach 3D imagery. The real question, of course, is whether we can get one big enough to project a life-size image in a cubicle.
