Looking a lot like a workstation from the starship Enterprise, the Poetic Technologies Aura is what I'd consider a truly überdesktop environment. The Aura has quite a list of features: seven-way adjustable chair, space for up to four monitors, programmed rotation to take advantage of natural lighting, electronically filtered forced air and indirect ambient light — and that's just the tip of the iceberg.
Each of these general "systems," as Poetic calls them, are all geared to provide you the ultimate environment from which you can, say, control the world (cue Dr. Evil laugh). The only thing missing might be a brain-massaging helmet.
