At the low level, it's pretty straightforward to work with their dev kits. A Raspberry Pi + some jumper cables + a bit of python gets things going. There are some quirks, since for the most part the board is optimized for internal update speed, not for usability. I ended up putting together some code to update the display given a PNG file, including some basic dithering for greyscale. And I drive all that from screenshots of a browser running in a virtual X terminal on the RPi. The update speed is not the best (several seconds from screenshot to render), but that's fine for my use case, since I'm using it for slow-moving info (weather, bus schedule, tides, etc.) and I'm better at writing HTML+JS for UI than writing bitmaps.
