As the name suggests, the PRC (Personal Rockin' Computer) chair is intended as a workstation...of sorts. Although, these images suggest otherwise.
Seriously, the gallery reads like this is something you might purchase in a unassuming building with no windows in the bad part of town. Whatever it is, I wouldn't mind having one. It's kind of like a hammock and a rocking chair all-in-one. Too bad about the ridiculous $US4200 price tag though. [PID via NotCot via DVICE]
