There's enough space to fit a jump/hop/bob, but I couldn't figure out the right period to pass into S.

So _that's_ how to do a global! this.r??=1

there are a few easier ways, the most common is to check if t is 0 to init t?0:r=1

There's no wrap around of the bits so you don't quite get the patterns shown in https://en.wikipedia.org/wiki/Elementary_cel… but it's late and I'm tired!

p.s. change the 1 in the first line to change the start condition, and the 126 in the last to change the rule number
