Definitely!  I'm going to need a "vision" based target selection
in another app I'm doing.  Unfortunately, Manor doesn't always
let the rest of the hive know what he's talking about doing.

I also had a couple of questions to Alex about his app:

  1) Does each neuron cover an arc distance?  If so, it
     seems that 7 would give more like a 210 deg arc for
     the entire "retina."

  2) Is the radius of the vision arc going to be pre-defined
     for all bugs, or bug-specific?  And if it's bug-specific,
     will that radius be a function of ambient light in the 
     space or directed light?  And how reflective would the
     bugs be?

  3) Will the bugs both move and look at every time step?  Or
     is there another sequencing, like move, look, look, move.
