Oops, new MockTurtle is on CroquetSource, not SqueakMap (right now)
Dropped the spinners :(
but almost have some interactive scripting working :)
(try the 'x' key on the cube)(just a pastime until some real! interactive scripting is available)
and a little playing with the environment.
It is useful to have Howard Stearns' fix from Mantis #3613 (if it's not in the update stream yet) or run in fullscreen mode to avoid a weird problem under Tweak.
After loading this package, click on the Croquet button in the green Objects catalog to refresh the choices, then drag out the MockTurtleDemo (Master). There are several keystrokes recognized by the little cube dragger-painter. For more information, browse the class comments for MTurtle and MTDragger.
