Re: 2.8" TFT Touch Shield Keyboard
Nice job. Perhaps you could post up a description of how it was accomplished. I'm sure others are interested.

This demo is a modification of Clay Furman's work (inspired by an Adafruit tutorial) found on the Arduino website. Hardware is described in the video. Arduino sketch follows:
