Very cool project. 2 questions:

1. How did you find working with the Sharp Memory display as a tinkerer? Did you like building with it and would you recommend it? It's pretty new tech to me and I've been mulling whether to splurge for it for a potential pet project of mine.

2. How's the refresh rate on it? Judging from your video it looks pretty dang swell. It looks to be a lot faster than the typical 15hz one sees on higher end e-ink displays available right now.

Using the Adafruit breakout board, I had no problems other than an SPI bug in the Arduino core. Be warned that they are fragile when not protected, I sheared off the flex cable on one which was not fun.

Official refresh rate is ~25 hz, unofficially they seem to be able to go a lot faster (2-3X) if you don't mind increasing power consumption. And it's faster if you update only some lines. But by then you have run into a limitation in how fast the liquid crystal can respond.
