#Life 1.05
#D Venetian blinds
#D This is a finite version of the infinite p2 oscillator in which
#D rows alternate full, full, empty, empty, full, full, ... Two types
#D of edges are shown, one perpendicular to the rows and one at a 45
#D degree angle. (It's easy to prove that there's no p2 edge parallel
#D to the rows.) Also shown are 3 type of corners where the edges
#D meet. This partly answers a question of John Conway's: What's the
#D maximum average density of an infinite p2 pattern, and can it be
#D obtained as a limit of finite p2 patterns? This shows that 1/2 is
#D a lower bound. Hartmut Holzwart showed that 8/13 is an upper bound.
