Projecting onto glass
Alright here's my question, I know I've seen it done a couple places, the first image I could find as an example was just this :
http://www.en.dnp.dk/data/4418/3791/4418.jpg# (just see below)
What kind of glass do I need to do something like this? I'd like to build a table of sorts out of glass with a projector built into the frame under it to project upwards onto the glass, then eventually perhaps adding an IR sensor and work towards building a touchscreen/MS-Surface-like table. Any thoughts? Obviously its not normal glass or the projector would just pass through it

I would have to agree, I have tried most everything and ended up using a similar material to project on glass with, it was so much easier and more effective then the sandblasting for me at least. much success

There is a much easier way that I have used, it takes minutes and no chemicals. http://www.ssidisplays.com/looking-project-glass

Has anyone tried sandblasting a masked off area and then projecting onto it?

Hello guys, last months I had to project onto a glass surface for a university exam, so I put a little research on my blog and I'm actually trying to list all the possible methods. I just post down the link if you're interested

Finally me and my group used a video retro-projected on a glossy paper layer (or acetate vinyl) on a plexiglass panel. Works quite good, and it's economic even if you can't get complete transparency.
What about sanding glass? Has anyone tried with it?

3M has a product line called Vikuiti for this. You can cut it into any shape and stick it on glass for projecting from behind. It is a little pricey, but the effect is amazing.

Or any idea if this would be easier with some kinda of plexiglass? It might be cheaper/more suitable for this project anyway since its lightweight, but I'm not sure if its possible with plexiglass, but then again I'm not sure hwo to do it with glass :(
Since the cost-effective way is to use a frosted surface, plexiglass may be the way to go - it shouldn't take much more than a light sanding to make the underside of the tabletop frosted enough to see the image.
Or
A large sheet of tracing paper under the glass would definitely provide a suitable surface, as long as you don't want to see through the tabletop when the projector is off.

Someone I went to college with did a lot of projecting on glass. I don't remember exactly how she pulled it off. I think it was slightly frosted on the top side.
Oh... when they do it in store windows they use this stuff called "rose glass" or something like that. It has a special kind of one-way tinting and is very expensive.
