Matt Williams has posted a Mach II conversion of my Canvas Wiki project. His blog entry talks about what it took to convert the application from Model-Glue to Mach II. This version, of course, is not an officially supported version, but Mach II users may find it interesting.
As just a quick FYI, I do have some bugs reported in Canvas. I’m hoping to get a Soundings update out this weekend and will then work on the Cavas issues.
