Can anyone advise on a good source for fresnel lenses? I have been interested to see how they are used on a number of projects detailed here including those used on 17" screens. We have tried using a lense from a back projection TV but without any success.. All suggestions warmly welcomed.

I ordered some from 3dLens several years ago.

3Dlens.com is indeed a good source. I used their F550 lens for 17" LCD (4:3), but it can be used up to 19" LCD (4:3).
More info on my experiments can be found on http://www.simprojects.nl/3_lcd%27s_with_3_fresnel_lenses.htm

Great video btw.. I love how your sim is very modular and easy to set up. I think I'll use the monitor design with the aluminum panels, love it how it just slides right in!!

Thanks! I used 17" LCDs mainly because I have a height problem in my attic.
If you can still find them, I'd suggest to use 3x 19" (4:3) LCDs in similar setup, which should give you the best view with the F550 lenses.
