I had a great talk today with Google open web standards evangelist Brad Neuberg about one of his projects -- a high quality SVG-in-Flash adapter which allows SVG graphics to be shown inline, complete with scripted interactivity, in the vast majority of Internet Explorer clients.
Using Flash to implement open standards in older browsers always makes me feel subversively happy... ;)
There are a lot of possibilities with SVG, which become much more exciting if we can do in-browser previews and interactivity for a majority of users. I've written up some notes on the tech blog:
