I’m also using sandblasted glass for my setup, but there is almost no grain, a friend of mine did it so he new that i needed the best quality. He gave me a sample of acid frosted glass but I cant see the difference with sand blasted frosted galss…
I’ll do some nice video with a cam recorder as soon as possible this week…

I’ll be looking forward to seeing your video wink

Hmm, so how noticeable are the projector hot spots when actually using the table?
Also, how many lumen’s is the projector you are using?

Alright, would the hotspots be the same with tracing paper?
Also, is there any way to reduce them?

well I dont really see a real hotspot, not as you can see on my quick video which has been recorded with a crap webcam.
I dont feel any problem with such brigh image at all. Hotspot can be reduce by changing the angle of projection, or use a different projection material, but i like it the way it is.

Alright, I think I’ll go with the sandblasted glass.
Contacted a local dealer and they say it will only be $89 (CAD). As long as it works, I’ll be happy smile

I’m trying to figure out if I can use something like Armour Etch to get the frosted glass. Mashine Gun, you said you saw Acid frosted glass. Is that the same thing?
