EDIT: After reading KLin's response, it's awesome how 21322314 has the recursive property of this sequence. It's something that should be in Godel, Escher, Bach: An Eternal Golden Braid. I wonder how if this sequence converges when you take any integer as the first number.

Starting with any number 1-4 you end up with that same sequence

I've yet to try 5-9 or 0 though..let's see...

#### Rubycon

It has to be evenly divisible by eight, the number of legs a spider has.

Starting at 0 it converges to 1031223314..too lazy to try 5-9 though.

Maybe it converges to the same thing except that the 2's are replaced by 5's? I dunno, just a guess.
