Damaru shows how to turn a Kindle into a monitor using a Raspberry Pi.

Using the Kindle as a screen, Damaru use a Raspberry Pi, a couple USB cables, and a keyboard to create a very minimal little computer. You do have to jailbreak the Kindle for this to work, but the rest of the process is pretty simple. From there, you only need to run a few things to get the screen sharing to work, create a system for automatic login, and you're done.
