Notice that, just as I said above, the end result is only a few frames per second, and even then the image quality suffers due to the reduced color pallet.

At first I thought someone had written real full blown video drivers, takeing advantages of the compromises I mention above (low frame rates, reduced grey scale), but sadly this is just a hack that apparently involves converting the video to a giant animated-GIF and playing it using the animated-GIF rendering in the web browser.

The reason it works at all is that the GIF rendering in the web browser on the Nook has already been tweaked a bit for eInk, and takes advantage of a reduced color palet and the quickest possible refresh.

In any case, animated GIFs have very poor video compression vs. image quality and no sound encoding capability, so it's really not practical to convert full length movies to this format, and even if you could, it will eat the battery and put a lot of wear and tear on the screen (an eInk screen is electro-mechanical and can eventually wear out

But it is interesting, though like the dog walking on its hind legs -- it may not be done very well, but the wonder is that it's done at all.
