Hmm. Etoys taught me how to use squeak. Basicly the Etoys "safe" environment taught me that it was easier to get things done if I focused on using the more dangerous but less restrictive environment it was written in.
Karl is right about the restrictions of the tiling system. While I found some easy ways to modify a picture that comes from a .gif file. I couldn't find a good way to do it in the tile scripting system.
Its a good ability to want. So I think you raised a good question.
You've just thought of something other's haven't addressed.
I intend to play with is some more. If I come up with something I will let you know.
Yours in curiosity and service, --Jerome Peace
