I am asking you, because I kinda stole your scenario. So I thought you wouldn't be ok if I would upload it.
And what exactly do you want to share with me?
Very good scenario, but there a some things that could be fixable.
Why are the "color balls" ovals and why is the mouse ball acting weird?
If you are interested, I could upload a paint scenario without mouse problems and round color balls, so you could take a look at it (+ the source code).
