I like the idea of using a binocular as a projector (but of course, don't ever actually look through the binoculars). At least then it is somewhat cool, compared to the dull pinhole method.

Hope them are cheap binocs, RW!
You can damage the optics from overheating!
Plus the image you project will be too bright to safely observe with the naked eye.
