Houndstooth is a period 2 agar whose unit cell measures 4×4 Life cells. In the figure below, cells which are always alive are black, during even generations blue, during odd generations red, and otherwise white. Unlike Venetian blinds or zebra stripes , its unit cell is finite in both directions. Unlike the phoenix squaredance , it contains cells of all phases and durations within its period.
