Let's say PI=3.14159265358979323846264

The name of this piece is I={..,PI,..}  ("Pie in your eye")

It is algorithmically generated from a very terse little bit of C code.

Basically, the idea is this:
 * You have a little virtual circular world of unit radius, which consists of all the
   real numbers in the range [0.0, 2.0 * PI] inclusive.
 * The world is populated by a maximum number of PI^PI of little travelers having
   the following attributes:
      - A lifecycle lasting anywhere from (PI)ms to (PI)s
      - A triangular amplitude signature, depending upon the traveler's age,
        in the range 0
      - A current velocity, initially equivalent to that of a parent (the ancestor 
        traveller has fixed value), where velocity is limited to the range 
        [1/(PI^PI), 1/(SR/PI)]
      - Periodic directional force vectors (ie:  periodic bursts in opposite
        directions), where the period is in samples and limited to the ranges
        PI to PI^PI^PI (Remember, F = ma, and these travellers always weigh 1, 
        therefore F = a), and the acceleration is limited to the range 
        [Vel*0.00001, Vel*0.001]
        
Let the little buggers breed, and listen to the results.
