After continuously reading about how you have to spend $2000 for a good screen and people saying there's no way a painted screen would work (other internet forums) even with $200 Goo paint I figured I would at least try and see what $12 worth of paint would do on a spare piece of drywall I had.

I set it up in my storage shed while we're building the room, and I think the results are simply stunning. The projector is an Optoma H31 ($1100) and the setup I have now results in about a 90" screen. Half the screen is painted ordinary flat white, and the other half is eggshell white with silver metallic mixed in. The final installation will make about a 130" screen

Of course you can't get the full impact without seeing it in person, but here are the pictures (at the bottom of the page):

Don't let anybody tell you that you can't make a DIY screen with ordinary house paint. This thing is awesome.
