Hahaha, i know a friend that built a atari when he was in university.. pretty cool . Anyways, for black plastic i suggest (probably already know this) make it not as black, more like a dark grey and make it an anistropic . Well, thats what i would do.. probably would come out not too nice anyways.. haha. I recently added an ambient light to my scene though, and brought it up and north west from my object, when i rendered it off it gave it a nice look.. maybe also try that . Just ideas. I will look around to see if i can find a black plastic shader
