Here's a great video clip from YouTube featuring a custom R2-D2 Nintendo NES. Here's a quick snippet from Ubergizmo.com: "Custom built by Mark Bongo of Major League Mods, this little astromech droid that could comes with the original NES console fitted within itself, where there is a cartridge slot located at the back alongside the power plug, audio and video plugs. In front, you will find the power and reset buttons which will respond in R2-D2′s now famous beeps and boops when pressed."
