There was a good guess or two in response to my last post, but you were all wrong (except Leah, who knew what they were because she had read about them before).
They're ProtoBlocs, and they exist for no other reason than to let people know they need to leave you alone without actually having to say "leave me alone." If the green triangle is on top, it's means people are welcome to come to your cubicle and talk to you. If the yellow ball is, it means, "I'm kind of busy, but if you really need something, come on over." And if only the red square is there, it means, "I'm way too busy to talk to you."
I'm not sure anyone really observes them, but I think it's such a funny concept that I just had to share.
