In the meantime, I made a cheesy video last night, showing some of the changes in quickly, and how the new CouchGrid and GridFilter work.
[Note that it takes blip.tv a bit of time to render out a high def video like this, so if the video is not yet working, you can check back later.]
[D'oh .... stupid blip.tv bailed on encoding my video. I'll try again with smaller files. Stay tuned]
