Apart the obvious usability to any electronics hobbyist of a project like this what i liked was how detailed is documented.
The controller uses an STM32F0 ARM Cortex M0 MCU to control a 640x360 LCD from a Sony Ericsson Vivaz cellphone. The firmware is built against Andy's open source stm32plus C++ library for the STM32.
