My talk on Blend for HTML, given at the Build conference yesterday, is now online.In the demo, I create the UI for a simple casual memory game, beginning with clean, UI-free, semantic markup and the backing JavaScript code that goes with it. From early 90’s browser look to Metro-style in less than an hour 
I also posted matching demo files in the VS sample gallery, in case you want to play with the demo app, or if you want to try building the UI yourself.
Have fun!
