The art blog continues! For your viewing delectation a TRUE three-way plaid. Done (cheaply) by using three sets of 30% opacity RBY stripes. First two sets generated a pattern following the third set of lines in which two of the strips had all of the primaries and the third had none of them. Adding red or blue to the third set meant no pure red or blue triangles, which looked crap, so I sacrificed yellow there. Plus some hexagons because hexagons are cool.
