What?
Tomomi Sayuda may have a nice bee-hind, but I have to say that I'd need a bit bigger of a scanner. Tomomi has designed a chair, referred to as the "iBum," that essentially scans and photocopies the sitter's tushie as they sit in the chair, then spits out the copy for them to scowl at stare at in amazement. Tomomi says that "the arse is the window to the soul." In my case, it is the sliding glass door.
From Apartment Therapy:
I believe that human buttocks are one of the less discussed and focused part of human body. In this “iBum” project, I would like to reveal the visual of this less popular part of body without notice. The chair reveal human unconsciousness and reality. When audience sit down on the chair, a scanner on the top of chair start to scan people`s buttocks automatically. Then the scanned image is printed out from the right hand side of the chair. A sensor is detecting people`s existence all the time. So people will not realize the existence of the scanner. Without notice, the photocopy of the bum will arrive next to the chair.
Here's some video – whereas Tomomi looks kinda bored as she waits for her buttcopy, one woman goes as far as to smell her copy, just to "make sure," I guess:
