DIY: A deeper view into the Portal gun

Well, that answers that: after wondering aloud just how the hell cosplay constructor 'Volpin' created the previously featured Aperture Science Handheld Portal Device, Gamedaily updates with an in-depth feature on its assembly.

'Volpin,' it turns out, is Savannah college student Harrison Krix, who -- after creating the first for his own personal Chell-belle Emily Keith -- is doing a second for Portal creator Valve (and, even more ambitiously, a life-size BioShock Big Daddy costume [!!]).

Oh, and the answer seems to be: just lots of foam and tubes, really.
