Check it out, my AAXA mobile projector. It's a new battery powered mobile projector, weighs about the same as my cell phone and projects a 640x480 picture. While it's not HD, it's good enough to watch 40-50" TV shows at night

I've attached some of my pictures... The video is 40-50" size picture at night... It's pretty cool for what it is

Works good with the PSP too!
Now I just have to wait for someone to build one into my PSP!
