My next arithmetic circuit will multiply two binary numbers together. How are you going to accomplish that? Are you going to use a grid method with AND gates, or use shifts and addition? I think that the latter method is more suited towards your style of computation. ideally with decimal (or hexade...

Dave Greene discovered a counter-example to popular belief, IceNine, a massive seed that grows very slowly, quadratically, and unstoppably. This is characteristic of a rule like Seeds or 34 Life, except IceNine requires a much larger critical mass (about 10 megapixels). Yes, this does grow irregular...

Your set/reset logic looks interesting, but I don't understand the point of the two block glider collisions; why not simple vanish reactions? Oops. I thought that reaction was a vanish reaction! My mistake - I've altered my post to compensate. Thanks for noticing this error. Congratulations on the ...

That's quite an interesting pattern; it constructs the rakes bit-by-bit like a production line. It's admittedly not as compact as the other rake gun, but that's probably because you just wanted to make a functioning breeder rather than trying to break any space records. The smallest period 120 I kno...

(This thread immediately caught my attention.) My first contribution: a bridge for p30 glider streams. I like it! It thins the p30 stream into two p60 streams and crosses them individually, before recombining them? The reason that Dean Hickerson's is more compact is because it uses XOR logic to cros...

That's very impressive. Did you write a Golly script to generate this? If you used a multi-colour Life equivalent like QuadLife you could make a full-colour printer. You can obtain the Golly rule table from: http://ruletablerepository.googlecode.com/files/LifeColor_FrancoisBoisson.zip (Compatible wi...

For your information, Mitchell Riley discovered (rather than engineered) a switch engine puffer with only 38 cells : x = 135, y = 41, rule = S23/B3 133bo$134bo$130bo3bo$131b4o4$130bo$131boo$132bo$132bo$131bo3$133bo$ 134bo$130bo3bo$131b4o9$96bo$97bo$93bo3bo$94b4o8$3bo$4bo$o3bo$b4o!

I am working on a different approach for sending diagonal lightspeed signals. A simple diagonal line of cells, the simplest fuse, burns cleanly at the speed of light. I have already worked out easy ways to send a 1 or a 0 and detect it at the other end. The question is: Can a simple diagonal fuse b...
