Ball physical model of bouncing object


superclass: UGen



models the path of a bouncing object that is reflected by a vibrating surface 


*ar(in, g, damp, friction)


in modulated surface level

g gravity

damp damping on impact

friction proximity from which on attraction to surface starts

// mouse x controls switch of level
