That only applies to a full-fledged GUI, complete with listeners,
though - all the OP wanted was a simple canvas to which he could draw.
I've already posted a working proof-of-concept of a canvas with a
thread to update itself every few milliseconds, controllable from irb
- I see no reason why that can't be extended to a more featureful
drawable object that works happily alongside irb.
