These Portal wares were some of the last I designed for the 2012 con season! They made their debut at AWA back in September.
I'm super late to the Portal bandwagon but I finally experienced the two games a few months ago and they're totally awesome! I'd been wanting to make a test subject badge since then, but I wanted to wait until I sold out of some other designs first.
I guess it's kind of weird that I didn't make any companion cube designs. Don't really plan to though, since so many artists already got that down, lol. All the love to Wheatley and Space Sphere.
