Have you ever popped some food into the microwave, hit 3-minutes on the timer, and then hung around with literally nothing to do while waiting for the food to be heated up? Well, if the Castoven ever becomes a consumer product, you might be watching YouTube clips in the future. This prototype microwave sports a built-in 10.4-inch LCD display on the door, along with a pair of speakers. While it needs to be hooked up to a computer to work, it will find and play a random YouTube clip which is similar to the length of time you’ve set on the timer, cool huh? Check out a video of it in action here.
