I liked getting to see the different robot designs, I think if there was something I could do while waiting, I would have the patience discover all of the robots. Also the money button was scary ;(

Was there anything to do outside of just watch the robots go around the loop? I guess that's technically idle in the full sense of the word, but some more changing things would've been cool. Maybe like the robots would get stopped for some reason and you'd have to click on the things blocking them.
