I have most of the smaller ones done - animated-canvas, describe (with documentation this time), packed-binary, and uuid - with only table-panel left to go. Right now I'm finishing up the documentation for my new sesame library - an interface to the Sesame RDF triples store - that I'll release this weekend. [I need it for my 'real' job.] Then I'll move on to the 'big three' - science, simulation, and inference. They'll take me a while because of their size and complexity.But, I'll redo the graphics to PNG format at that time.

Sounds good; let me know if I can help; I'd be glad to crunch those files and spend five minutes changing "bmp" to "png" everywhere.
