Cool new pocket-sized projectors

This video is really cool, it is showing some new projectors.  They are super small and can hook to any device that has a video output and project it onto any wall.  It has a small rechargable ION battery.  I find this video very interesting because i love how projectors work.  I like how they can make the picture show up on a wall however big you want it.  If you have say a big screen tv, the picture will stay the same size forever, but not if you have a projector to make the screen bigger all you have to do is move it farther away from the wall.  This is related to informatics because its new technology.  Being an informatics major I will be needing to be keeping myself up to date with all this new technology that is being developed all around the world.
