I'm trying to remember the names of these things so I can google them... basically, they're patterns in the form of shapes, etched into rocks in south america. But I believe the catch was that they only appear when photographed. A typical example of one of these shapes would be a square, with a diamond on the inside, and maybe some diaminds and triangles. But they look very sophisticated.
