+
+* "bouncing" back and forth between two tiles.
+* repeatedly setting a pattern of tiles in the row.
+* setting a pattern of tiles in the row, and then stopping. what's the longest pattern that you can set before stopping? (this is basically the "busy beaver game")
+* processing an "input" given as the initial state of the row of tiles. maybe the bird can duplicate it? count the amount of specific tiles? perform arithmetic?
+* generating interesting visuals for your next algorave.
+* and whatever else you can think of!
+
+setting up the sixteen possible rules in the table can be a little bit overwhelming, so remember that you can "turn off" a rule, a column and/or a row by using the halting pose.

 # about
 
 jarotsim is inspired by {turingsim} as a simulator of turing-machine-based performances like {d-turing} or {mub}.
