Add a TFT screen and you open up a world of new uses for the Raspberry Pi. In this episode, we create a Bitcoin Ticker that shows the price of Bitcoin on Bitstamp in real time.

The TFT screen used in this video is available from Adafruit for $35. http://www.adafruit.com/products/1601

The code that displays the digits on the frame buffer is available here: https://github.com/anders94/framebuff...
