It has 4 interesting properties:
The area/number atoms in play grows without bound.
It actually does loop forever and never stop producing outputs.
Every atom that is pulled from the reagents onto the board is eventually pulled off of the right and put into the output.
Each production takes approximately 5 times as long as the previous one.
I have run this machine long enough to get to 6 products. It took several hours. Here I'm showing the first 3 productions plus halfway to the 4th as the captured gif version doesn't really do this machine justice since it captures the very first one, and the ones past 3 take a really long time. And once the machine reaches about 7000 cycles, the game really starts slowing down.
