Someone over on the Infinity forums pointed out that Tech Deck skateboard park pieces would make good Infinity terrain. Seeing as how I had to hit Target today for kitteh supplies, I dropped by their toy section. Lo and behold a bunch of their Tech Deck stuff is on clearance! I am not surprised given how expensive this stuff is MSRP and I really can't see kids getting too much into this. However, as Infinity terrain its perfect.
I picked up this set for $15 on clearance. It consists of two sections that connect underneath with plastic pins. The construction is solid, befitting a toy designed for use, and the paint job is subtle but sufficient for gaming purposes. It is nicely weathered and has two graffiti graphics that look cool and suit the nature of the terrain. Honestly, there is little I would do in the way of additional painting except perhaps to add some additional detritus in the corners.
I found the curves of this specific piece to mirror my vision of the Infinity architecture. Moreover, the piece looks good setup next to the Topo Solitario IKUBE series of containers. In fact the back of the Tech Deck piece is exactly the height of the IKUBE containers, so you line some containers up and use them to climb over the back of it. Overall dimensions are 22" long by about 8" wide and its about 2" tall at its tallest point.
