That's the logo I meant. I mean it's not an exact depiction of the position in go, but I had imaged that the three lines were an abstracted representation of three black stones on three sides of a white stone that's not depicted in the logo.

Actually it seems like this is just a coincidence though (and it wasn't supposed to represent a mountain either):

> Opperman designed it with two things in mind: the first was that the overall silhouette was to look like the letter A, matching that of the company, while the second was that its three "prongs" were based on Atari's first hit game, Pong.

How about the other way around?
