Torpedo Digital Game and Movie Projector allows kids (or those of us that are big kids) to see their gaming on a larger scale. You connect it to your video system or game setup and you can display what you would usually see on your simple TV screen, somewhere else, in super-sized mode.
Projects in a 960x240 resolution and has built-in speakers so you continue to hear the same gaming sounds you're used to. You can also plug in a pair of headphones for a quiet experience, but I think if you're projecting it up there that big, you probably want projected sound, too.
You could also set up with a DVD player for larger movie displays...could be fun for parties or a get together.
