You will only need to take your cell phone or iPhone and a tiny portable projector.

A company called Microvision produces a tiny, portable projector that uses red, green and blue lasers and a single tiny micromirror to project an image much the way old cathode ray tube televisions did, by scanning lines to create 60 frames per second. The whole projector fits in the palm of your hand, but a lot of that size comes from the battery; if you had an external power source, such as a USB, this thing could be as small as your thumb.
