 This is an example that displays many of the capabilities of NetLogo 3D.
 
 ## HOW TO USE IT
 
 The SETUP button creates BALL-COUNT balls poised above the "floor" of the world. GO releases the balls and "gravity" pulls them down.  The balls will bounce until they lose momentum.  If the COLOR-SPEED? switch is on the color of the ball will be scaled the speed it is moving.  If the TAILS? switch is on the balls will leave a trace of the path they have taken.
