Folks -
I now have a compact and reasonably efficient implementation of wavelet transforms in Squeak. I based it on Mac Cody's article in Dr. Dobb's Journal, so as to be able to leverage off his documentation and examples. Those can be found at...

I will issue it as a squeak update in a week or so, but if you want an advance copy, send me a message offline.

My first cut at fun math stuff for sci/eng types, including a reworked and much better tested version of the double dispatching math stuff has showed up at the UIUC arhcive ftp://st.cs.uiuc.edu/Smalltalk/Squeak/goodies/EngineeringMath/.
For an overview and more detailed description, read ftp://st.cs.uiuc.edu/Smalltalk/Squeak/goodies/EngineeringMath/EngineerMath.html.
