When we first saw a photo of Sharp's XGSV100W Conference Series data projector, we thought it might be a prop from Lost in Space and started muttering "Warning, Will Robinson" under our breath. Colleagues quickly declared our behaviour was that of a bubble-headed booby, because they realised the projector's rotund form has nothing to do with robots and instead offers you the chance to rotate it by 180°.
You can, of course, do that with any other projector — you just pick it up and point it in another direction. But that's harder to do with a roof-mounted projector and that's where the XGSV100W wants to shine (pardon the pun), by adding flexibility to projectors that have already been cemented to the ceiling.
Sadly, the $5,499 projector can't rotate all by itself; it needs the ANSV100T motorised mount to help it twist, and that will cost you an extra $1,999.
As Dr Smith may have said: "Oh the pain, the pain!"
