extraneous commentary by hvm

Could these be candidates for inclusion in the list of patterns (oscillator)? There is considerable resistance to proliferating these lists unnecessarily, but there are few pages for high periods, and these two have an impressive symmetry. The period 6 oscillator has a beacon fighting a piston-scrubber combination, which could possibly be promoted into an agar or something, but in any event the preblocks confining a group of p-s's ought to be of some interest. The period 4 oscillator is so symmetric it is just plain beautiful.

Huh? Who is this? No sign in this comment...--David 10:25, 2 December 2009 (UTC)

Happy birthday

If I may infer from your update this is today. All the good be with you! --Methodood 20:59, 8 January 2010 (UTC)

And, as it is customary to give people gliderless spaceship guns as birthday presents, here is a compact p150 gliderless MWSS gun:

JOY!

I solved Calcyman's problem #36!
