Tom Rokicki's radicaleye.com site appears to be down, including his archive of Paul Callahan's and Dean Hickerson's old websites. Any news on this? Is this a temporary outage? Or is it really gone?

Here's an idea for a pattern search. I don't really have the time to do this search myself, but let me describe the general strategy, in case someone would like to take it up or comment on it. 3 steps: 1) Make a database of simple stable patterns (collections of still lifes, with less than N cells) ...

MikeP's loafer-to-herschel converter is amazing. That still life looks so dense and vulnerable, but it just repairs itself. How did he find that? Has anyone applied the same search technique to look for *WSS-to-herschel conversions? Can we dare to hope for direct *WSS reflectors? The repeat time of ...

Nice. Herschel and block at gen 90. Unfortunately, the herschel is travelling back along the path of the incoming loafer, and quickly emits a glider that destroys one of the fishhooks. Can a herschel conduit still be attached? It doesn't look hopeful, but I haven't played with herschel conduits in y...

Here are 5 stable loafer eaters. The first 2 have already been seen in this thread, but the other 3 are new: x = 73, y = 49, rule = B3/S23 64b2o$25b2o37b2o$26bo$26bobo$27b2o$5b2o2bob2o22b2o2bob2o11b2o9b2o2bob 2o$4bo2bo2b2o22bo2bo2b2o12bobo7bo2bo2b2o$5bobo27bobo17bo9bobo$6bo29bo 29bo$12bo29bo29bo$10b...

Back on topic: Congrats to Paul Tooke on the loafer-based sawtooth. I have independently verified that this is the only collision back-end *WSS collision that does not destroy the loafer, aside from the LWSS variant which destroys the LWSS and leaves just the loafer. There are 579 possible back-end ...
