This is Gary. Gary is an 8-bit man made flesh.
He is not, as you'd first suspect, a statue. Or a giant LEGO creation. He's actually a costume, worn by a she, built by Kiel Johnson and Klai Brown, and with enough joints to enable the wearer to get around. He was made for a Toshiba commercial, but will surely get more mileage as a party costume, or suit for hire for those with a pixel fetish.
You can see a complete making-of at Hyperbole Studios' website below.
