Mini Programs in ><>, #2

Today I made something like cellular automata in ><>! It wasn’t working until I figured out that ><> reads characters from the grid as numbers, but stores characters by interpreting the number as an ascii code. So if I try to store 9, it writes a tab character (ascii 9). Adding 48 fixes the problem. Here’s the program:

v v
> >0123456789v
  v          <
  >          v
  v          <
  >          v
  v          <
  >          v
  v          <
  >          v
  v          <
  >l3(?v1+@3+@86*+@p
       >00.

Run it online with the ><> interpreter (the site is down, so that’s an Internet Archive link.) The program reads the open grid section, writes some numbers to it, and then repeats.
