More displays just arrived:

I now have three goals:

• write a GIF decoder in C and include it in the firmware, so that animated GIFs can be displayed,
• redesign the PCB with a QFN package of the chip, and try to make it all thinner,
• figure a way to get rid of the physical switch, so the whole thing can be cast in resin or something similar.

For the second point, I'm considering making a hole for the battery in the PCB, and moving the microusb port and the charger electronics to a charging station.

For the third point, I guess I would need to add a mosfet on the backlight, figure out the sleep modes of the MCU, and make it wake up on touch or add an accelerometer for waking up (and also for some interactive animations).

However, for now the first point has priority.
