A representative from Texas Instruments had showed up in the X.Org development room yesterday to show off one of their new products: a very tiny projector. This projector has a mini HDMI integrated connector for video input, uses LEDs and DLP technology for display, and can easily fit within your palm.
Right now this mini projector is only capable of displaying at standard definition resolutions, but within a few short years Texas Instruments will likely have a high definition model. This projector is very easy to transport (well, it can fit in your pocket) and pulls just a few Watts of power.
Below is a video of the short presentation.
