Or sketch morphs.

I did some hacking to add a hue, saturation, brightness rule to 
BitBlt. Take a look here
http://swiki.gsug.org:8080/sqfixes/1630.html
Some parts of this is written in a subset of smalltalk

I also did some work in plain smalltalk
http://swiki.gsug.org:8080/sqfixes/1603.html

Also take a look at this project:
