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.
