I’ll be getting into the Degrafa demos business pretty soon, and will be adding a Degrafa page to the blog just for tutorial and related links. If you haven’t looked into Degrafa or are curious about how to get started, then check out the excellent introduction at InsideRIA. There is a great samples section at the Degraf site as well as a complete learning page.
Some misc. tutorials you might find of interest (a few samples from my Degrafa bookmarks – yes, they need to be posted to Delicious),
