#D      Here is a a beautiful 'waffle' for the range 7 Box Larger than Life rule
#D with birth interval [75,170] and survival interval [100,200], after 90
#D updates, with all 0's boundary conditions. The initial configuration is
#D a central lattice circle of occupied sites with radius 12.
#D 
#D Starting from a 50-50 random mix of live and dead cells, the dynamics
#D produce a familiar nucleation scenario - most of the space relaxes to
#D all 0's, but isolated pockets of activity form seeds for spreading
#D colonies of 1's. Try it! Early on we observe an assortment of waffles,
#D most imperfect, but some highly patterned and nearly symmetric. Later the
#D imperfections take over and cover the space with another variety of
#D pseduo-random 'seething gurp'.

#D Intrigued by the delicate transient droplet patterns, Kellie Evans segued
#D into 'engineering' mode in search of the perfect waffle. She discovered
#D that for the LtL given here, if we start from a radius 10 lattice circle,
#D then the waffle appears to grow 'perfectly' for more than 70 updates before
#D beginning to unravel.
