Ruby Bindings Animator problem

Wed Jan 7 11:02:36 CET 2009

hmm

All I know that makes it special is the animator is a singleton class,
the self() function returns the instance and probably allocates a new
one

Lots here, First the results of the test app, then the test app below it

Along with what debugging info I could get ..,, sorry my symbols are
incomplete.

Results:
