In case the HD camcorder with built-in projector is not for you, then you can have a look at this OptiMax-II iPhone Video Projector if you have an iPhone by your companion.
This iPhone Video Projector provides an awesome functionality to ‘zoom’ your iPhone content from it’s small screen to your wall at 110-inch large (diagonally) at the range of 20-inch up to 18 feet away.
This is the device that projects videos from an iPhone. The LED-illuminated projection system provides 557 x 234 resolution with its 4:3 native aspect ratio, projecting videos on a screen or wall up to 110″ diagonally from as close as 20″ up to 18′ away.
Playing audio through an integrated sound system, its two 3-watt titanium drivers integrate with the on-board dual 7-watt amplifiers to produce crisp, robust sound. It can also display videos at 16:9 aspect ratio–the same used by high definition televisions.
The 15-watt LED has a 30,000-hour lifespan and provides a brilliant 800 lumens for clear, bright pictures and videos. Manual focus. Plugs into AC with included adapter. Includes remote. Supports iPhone 3G/3GS and iPhone 4 and 1st and 2nd Gen iPod touch.
