   I've often thought of that.  You'd need eyes bigger than Zoey Daschanel   
   and Irene Bordoni combined.   
      
   You know that famous chaotic function that can be modelled with a   
   circuit of 2 multipliers and fed into a scope in XY mode to produce a   
   pair of spirals?  There's a complete circuit on Paul Horowitz's website.   
   I might have made one for fun if the multipliers weren't $20 each.   
      
   Well, it would also be neat to put one in the cabinet under that old   
   scope in your lobby.
