This piece was done for a show titled 'Heroes' at Cal U. While the Turrets from Portal generally aren't regarded as 'heroes,' I decided to pick them anyways. For the show, I placed one on the wall and hid the other eleven, asking people to find them all. I wanted it to be interactive. The theme I was going for was: you probably wouldn't notice just one, but when you start to repetetively see them, then they catch your attention. To me, they are all a single unit. I had a lot of fun making them and everyone else enjoyed looking for them at the show.
