Projectors cost hundreds of dollars and you can’t just take them anywhere. A cell phone projector costs $1 and you can take it anywhere, and if you drop it along the way, its not a big deal.
NEED: Shoebox, Paperclip, Smartphone, Magnifying glass ($1 at Dollar Store), or a large aperture lens (from an old camera or other), Exacto knife or other sharp knife for cutting paper, Electrical or black duct tape
Trace the outer edge of your lens or magnifying glass onto one of the short sides of the shoebox. Cut out the hole with an exacto knife. Cut a hole at the back for your cord. Tape around the hole to keep light in. Make a stand for your phone inside the box with a paper clip. Turn off “Rotate” on your cell phone, so your screen can be placed in upside-down and turn the screen brightness up. Place your shoebox where you want it, and place your cell phone inside at the right distance (so that the focus is clear). Do fine focus by moving the box.
Projection seems to be a big interest direction for technology right now, but it doesn’t seem like they’ve figured out how they will really use it except in theater applications (home theater included).
Ashton Kutcher recently tried his hand at adding a projector to a laptop computer. We’ve seen the futuristic cell phone projectors that can already be made. I even heard that some of the newer invisibility suits use projection of some sort. This is a great way to get creative at home for a low cost. However, for those moments when you have people over you’re most likely not going to use this projector that you have made. Therefore, looking into the various high definition or 4k projectors out there on the market maybe a better option when wanting to watch a film in high quality. Or better yet, why not go a little bit crazy and treat yourself to a fully inclusive audio-visual home cinema set-up. Sure, it might seem like an investment, but it’s likely one you won’t regret.

One of the more interesting applications I’ve recently seen was a 3D projection application: 3D models (of a city or something) were created above a screen.
3D models seems to be an area where projection would really be handy. 3D is nice, you can throw a movie up real big on your wall. But you can’t just go out and buy a 3D model anywhere, and its not as good to view a 3D model on a 3D screen (like auto-CAD or city planner). Can’t wait to try something like that out — sculpting in 3D projection.
