Rossum built an e-book reader for the microtouch. He wanted to use the common e-book format epub. But unfortunately since the format is actually a compressed set of text, html links and images, it was too much for the 8-bit microcontroller to handle.
To overcome this he developed a transcoding tool (epubgrider) to decompress the data, and format it so the device could handle it. Once the book is transcoded it is saved to a microSD card which the device reads and displays via the firmware he developed. Check out the video of it below.
