I had so much fun [1] with the MegaRAC® K1 [2] that I hooked the device up to my workstation at The Office (and you can hook a keyboard, video and mouse up to it, and still remote desktop into the system), then from my system used rdesktop [3] to get to the Windows box, from which I remote desktopped (um … yeah) back into my workstation.
The effect was much like pointing a video camera to a TV (Television) displaying what the video camera sees.

Just because I can.
