Many old Nokia cellular phones have graphical LCDs based on the PCD8544 controller. These are perfect for various electronic projects with microcontrollers. The interface is a two-wire serial type (clock and data), and some additional signals. The LCD supply is a single 3.3 V with very low supply current. This is not really a "hack"; we are merely re-using parts of the phone.
