Wouldn't it be good if someone could come up with a chemical concoction in a spray can that was clear as water when sprayed on a wall/ceiling but would have the properties of a film emulsion that would react with a projected image. Buildings could be given artwork like St Peter's cathedral painted by Michael-Angelo very quickly with a computerized projector that could expose images on even curved surfaces
How about a self-assembling display? Spray it on, and as it dries, the nano-bits align themselves properly, transistors and caps and LEDs, oh, My! Just apply a voltage to the paint as it dries, then wire it up and have a wall full of mountains, or snow, or Mars! Or your mother-in-law, 42 times her natural size... 
If it was possible to make electro conductive paint to supply power then your ` paint with nanotube photo emitters' might work.
I thought I was being supportive of your forward thinking. Excuse me. 
Another application of such photographic paint would be that you could have your favorite shirt, dress, T-Shirt, tank-top, even jeans treated with it and then have images scanned on them. You could have an image of your beloved girlfriend photographically scanned onto your favorite white tank-top, you could have a photographic image of yourself placing an engagement ring on the finger your girlfriend on the day of your proposal scanned onto your white T-Shirt.
Ah! Big welcome to another romantic!
You can already put photographs on t-shirts....I bet you know this?
I'm just saying that what you want to do with clothing is already available~
Peace!

You'd have to apply the paint in total darkness (and I don't know if you've tried that recently but it's really hard), otherwise stray light would ruin your image before you had a chance to expose it to a projection, and then you'd need a way to stop the light-sensitivity afterwards or no one would be able see it without ruining it. Your "stopper" would probably be some other substance you'd have to paint on, and also in total darkness.
The paint wouldn't be like regular film emulsion. The paint would be applied in the day. The chemicals contained in the paint would produce true colors. However the paint would be responding to the computers projection in whatever spectrum. A laser projector could paint an image use the ultra violet spectrum as a code to the spectrum red to violet. Heck you could design paint to react photographically to microwave spectrum's from a maser.
Hi all,
I like Sapo's idea.
How about an "array of tunable quantum dots", wirelessly connected to your bosses skull. This would be a "can't miss" billboard version of the "mood ring". everyone would know, as they entered the building, how to deal with "the man" (or Lady), that day. Did s/he get lucky last night??

That's a pretty good idea. The real kicker is figuring out how to get a paint to change color based on an EM frequency and remain permanent.

For God's sake. Read up on nanotech, kids.
I was going to reason, state logically, and all that, but I'll let it stand at that for now.
Edit:I'm sorry, Ashibayai, that wasn't meant for you, or anyone else in particular. I'm just old and grumpy right now...
I have to go and be an HVAC tech tonight, and I don't want to.

There's actually a real old technique that produces "gum prints" on fabric.
It uses sun light to "cure" which is actually the process of exposure.
I don't remember offhand all the details, but I think it uses acetate paper to transfer the image through emulsification.
The process could probably be modified to produce something like this if you had billions of $ to throw at it.

Interesting stuff they've done with paint. Though why you'd want to study the science of how paint dries...*looks around for suggestions*

What the heck is this! Self assembling paint cans! Please, the idea is insane. What one sees being the perfect design, another sees the image having flaws. Pre-fab images are not the answer. 
Don't worry midwestern, the OP has been booted off physorg so he won't be back to post. The idea isn't so much insane as inane, but that's typical for this idiot
