Traditional gun vs gun was rather insensitive to displacement by x=2, y=0, t=0, but this one builds and unbuilds crystals whose exact length matters. I lost the initial conditions on that first run, but sometime around 26000000 it drilled the deepest debris tunnel I've ever seen. It finally died with two beacon boat-bit pulse dividers.
If you want a twin bees puffer or pufferfish, I can easily find them again in the census. --rwg
[clip] Holy cow, it's *not* invulnerable (gosper.org/mygunjammed.png )! Some time after 50000000 steps a fluorescence glider must've crept NE up the side of the diagonal column and nailed the glider launcher as it was peeping around the side. This was just another small, even number tweak of the initial horizontal separation. This is the first experiment that didn't end with the spontaneous formation of glider eaters. The only other outcome I can picture is eventual periodicity of the debris. Ideally, sprouting switch-engines for quadratic growth. In these bilaterally symmetric experiments, periodicity may be elusive due to glider (and even spaceship) commerce with the increasingly distant central column. Damn, the bad old days of screengawking have returned. --rwg
