erlang gs demo and wx

[Jerome Truong]

I'm trying to test some demos with gs on erlang but not sure how to view the graphics.

I cd to <erlang install>/lib/gs-1.5.9/examples and run erl -pa ebin

1>color_demo:start().

and i just get <0.33.0>, i'm guessing it's an object id.  

But how do i see what was created by the demo?

Thanks,
Jerome
