Utilizing a fixed projector screen when not used?

Any ideas of how a fixed projector screen can be utilized when not used with the projector?

Some TVs have an app that turns them into paintings when not used and I guess you could do something similar with a projector screen, but I don't like that as it would consume too much energy and add hours to my projector's lamp.

Another idea I had is to put led strips behind the screen, so it can be turned into a large diffused light panel. Maybe the LEDs can be of different colors creating an interesting light pattern, something like an abstract paining. But I don't think the screen will allow sufficient light to pass through.

Any suggestions?

Maybe use laser to do a laser light show. There are ones in various price ranges. Here’s an example:

It would require using the projector, but how about turning it into a "window" by feeding it with the HDMI output of an outdoor camera?

Here is an extreme example of the concept ...

Thanks for the suggestions.

I thought of a laser projector, but probably it is a bit too "flashy" and maybe not that cheap to run.

Maybe I will add a few small dimable RGB recessed directional downlights on the ceiling in front of the screen and use them to "mix" different kind of colors on the screen.

Something like this is inexpensive and would probably get the job done perfectly (without using up your projector bulb):

One other solution is to paint the entire wall with a screen paint eliminating the screen entirely. When the projector is off it's just a blank accent wall.

Looks interesting (if I can find the right pattern). I wonder if you can focus the beam to cover just a rectangular surface.

Yes, that is another option. But isn't screen paint a bit of a compromise when compared to an actual screen? Also I think the black border that screens have can make the image seem to have a bit more contrast.

You get a set of those holders with steel wire for approx. 20 bucks at Ikea (up to 200 inches long)
At my local printing press I can buy one piece of textile larger than 120" and have it printed with an image of my choice for less than $100.
Hang it over the wire and you have a huge piece of art in your room (maybe even use it like a curtain you can push to one side while watching).

I think I'm actually going to do this once my new screen is up.

Not if done properly with a well-prepared wall and the correct paint carefully applied. When thewirecutter.com did their big screen comparison test the best measured performance was by a painted screen, not a manufactured screen. It requires a lot more work but can produce great results. Anyone who decides to go this route can get good advice in the DIY Screen Section of AVS Forum.

This is what I'm doing in my basement -- I just project straight onto the wall. The projector is hidden also, so it's a totally stealth system when not in use. We had friends over and they commented that I should put a TV down in the basement, I then flipped on the projector and were blown away.

I'm actually projecting onto a fine grain stucco antique white wall and the picture is remarkably good. Never tried paint, but I'll bet it will look great. I don't have any issue with absence of a black frame in the basement, though that room is dimly lit.

What they suggest seems more like a wallpaper.

Now I think of it, paint will have an additional issue in my case: I plan to have conduit access on that wall (connected to the AV cabinet below) for when TVs become big/cheap enough (or maybe modular) so the screen can be easily substituted with a TV.

AV cabinets under the screen are very old school. Especially with a projector all AV components should be near the back of the room ideally hidden in a closet. For a nice clean look most prefer hidden components compared to a obvious AV cabinet with distracting lights under the screen. It also has the bonus of much more reliable short HDMI cables with just easily hidden speaker wire running to the front of the room for LRC.

The Screen Goo paint package tested included paper on which the paint was applied. Most DIY painted screens are done directly on walls and not on paper. There are many good options discussed in the DIY Screen Section of AVS Forum.

EDIT: I need to correct this as I mixed it up with another product. Unlike Goo Systems' other products which are all paint, GooToob is a wallpaper that is not painted. GooToob scored well in thewirecutter.com comparison review measurements while Goo Paint scored lower. Still, even Goo Paint measured close to Silver Ticket and Carl's FlexiWhite, so not bad overall. Paint is definitely a viable alternative to manufactured screens but requires a lot of care and hard work to get right.

I have one of those outdoor star projectors things made to shine on a tree. I mounted it in the theater to shine on my flat black ceiling. I turn it on once and a while, little kids get a kick out of it watching a movie under the stars. If the field is too wide just mount a mask between it and the screen/wall to block the unwanted parts.

I think @MississippiMan and others who have used his paint and method would says it’s not that tricky at all.
