I'm posting some pictures that were from an old post of mine, that showed when I got my projector up and running for the very first time. At the time I did not have an enclosure and the room got flooded with white light whenever the projector was on. The second set of pictures show a great improvement in contrast & colors after I had built a ghetto enclosure in about 30min out of foamcore and duct-tape. Hopefully tomorrow I will post some more pics for better comparison, and also post a series of pictures taken with a much nicer camera so people can see how big a difference just the camera being used can make in demonstrating your picture quality to others. I feel even the pictures that are after I built the enclosure do not show what I see when I run the projector, they are about 50-60% of actual quality.
Before Enclosure was built:
After Enclosure was Built. Much less stray light in the room.
I will get more pictures up tomorrow so people can see a better comparison, and also the quality improvement when using a higher quality camera. The "new" pictures should be much more acurate to what I am actually seeing.

Both of the above sets of pictures were taken with the same camera, in the same room, just with varying degrees of light. My Sony camera has a crappy auto levels feature so it really sucks at taking pictures in the dark. But it does give people a chance to compare the difference. Better pics to come...

Lots of Pics...
I finally have some more pictures ready of examples of the quality difference in the projected image, depending on whether or not you have an enclosure setup. Right now I have a Dukane 4003 OHP, and a 3M 6400 LCD panel. I have a cone shaped shroud covering the top of the LCD to the triplet. And have also built a ghetto enclosure around the OHP itself. The materials I am using are foam core and duct-tape for a quick mock up, and this material holds up well against the heat from the projector. The biggest problem I have had was using velco tabs to attach vent covers, on which the glue melted and they slid right off. I have now put duct tape directly on parts of the OHP itself, but depending on what parts of the tape are exposed the glue on the tape can become useless. I have the stock 410w FXL bulb that came with this OHP, but have put in an order for the 250w MH from DIYlabs for hopefully even further improvement. I will try and post some shots of the quick mock up enclosure I made with the OHP and panel so people can get a rough idea of how quick and easy it was. I am basiclly doing this for comparison, to plan how I will want to construct one out of aluminum once I have a good design planned out.
The pictures you are viewing are of an 8' foot wide by 6' foot tall projection. From about 11' feet away from the wall. The camera is taking pictures from about 12-14' feet. The angle is slighty different on some of the first pictures, but I am not currently using any special surface except the wall in my apartment, hopefully that won't make a huge difference in the comparison for these pictures. The color of my wall is an "off white" almost like an "eggshell white" with a very slight yellow tint, probably from smoke. The first picture in each set will be a sample of projection without the enclosure and the second image will be after I created the enclosure. The last two pictures of Pacman and DigDug are ones from after the enclosure was built and I just wanted to add them cause I liked them. Sorry no comparison there.
All in all I hope this gives people some good ideas, or motivation to improve their setups, as others have done for me. I am hopeing by february to have made major improvements over what I currently have. I will also try and post some other pictures for comparison with a different camera so people can see if this makes a big difference also.

Pictures of my Make-Shift Enclosure:
Here are some pictures of the very basic enclosure I have made. Nothing too special but it cost me next to nothing. I think it was about $1.99 per sheet of foam-core [required 2 sheets to make] and the "black" duct-tape was about $2.00 also. I had the grey duct tape around the house. It took about 30-45 mins to make, and I did it while the projector was running so I could see all the major spots light was leaking out from. All in all I am very happy with the initial results and I am planning on coming up with a concrete design to use in making an aluminum enclosure.

You can see on the sides towards the back I made special exhausts to vent heat & light towards the back of the room away from anyones viewing angle. A friend of mine suggested for a final design when I build an aluminum enclosure, I should copy the idea theaters use when walking in the the theater. The doors are basiclly 2 "L" shapes back to back. This helps light from entering the theater, when people come in.
You can also notice these pieces are removable so you can take the whole enclosure apart to get access to the OHP & LCD panel when needed. It's about time I gave my setup a good cleaning.

that is sooooo ghetto! haha I love it!
I also have a 4003 and plan on trying this really soon.
There is so much light which escapes from this OHP!!!
you're hoping for a dark room, and sundennly you switch this one and the room is fairly well lit with this thing :-/

Multiplexor,
Yeah I like this OHP projector a lot. It is much better than I expected when first purchasing it. I have noticed serveral main areas which I'm sure you have also, where a lot of light escapes from this thing. The bottom where the legs fold down, the two vent fans on the sides, and the spot where the lever comes out which allows you to switch your bulbs [also the main spot through the LCD panel itself. It used to almost project a viewable image on my ceiling as well as my wall.] Two other spots I noticed that were annoying, were the side with the hinge and the area underneath my panel. With this temporary foamcore enclosure I have made it blocks this light from coming right out at you, without restricting airflow underneath the panel. I am amazed by how much light this ghetto 😉 setup actaully blocks. Before my room was like you said "fairly well lit" and now it's much more like a theater enviroment. I have found myself becoming much more absorbed when I watch movies with it now. As you can see in some of the pictures, I have a blue shirt on in the first sets, and you can see me from below where the bottom of the screen is. In the second sets with the enclosure, I am wearing a white shirt which is even easier to see, and from below where the bottom of the screen is, it is pitch black. The matrix shot in the white room is a very good example of that. Anyway man, I'm glad you got a kick out of it, good luck with your designs, etc. I probably won't be adding anymore images anytime soon unless I can think of another good comparison. Maybe shots of the actual OHP in use, with and without the enclosure, and maybe the room itself with the reflected light before and after. I might also try some pictures with an HP camera I am borrowing from a friend to see if the picture quality is more acurate to what I am actaully seeing as these pictures are about 60-70% of the actual quality I see. Thanks for the feedback.
