There was a show, when I was a kid, that had robot cubes in it. Two different types of cubes would fight in space or on other planets. They had 'smiley' faces -- I think the good cubes had round/smooth lines, and the evil faces had pointy eyebrows and mouths. Anyway, think 'cubes with faces made of lines' and you'll know it if you've ever seen it.
Anyone remember the name of that show?
Oh... and, did anyone figure out what the hell it was all about? ;D
