Engadget have agood article on how to build your own HD projector from a washing up bottle and some double-sided tape. It sounds like fun, and I've always had a soft spot for TVs made of wood.
If that all sounds like too much trouble, US company Lumenlab have done the hard work for you and made a low cost projector that relies on a $30 bulb.
