I was watching with amazement , the video of 1024 architecture guys. playing live
http://createdigitalmusic.com/
and am most interested by the Skrims/ see thru screen layers they are using
it's seems like the projections are being sent to different layers on nthe stage
just how are they doing that? would love some insight

Are you referring to this video?

If so, it's the same projection on each layer.

Fantastic video too, thanks for sharing.

it's more than just the same projection… A mosquito net keep half of the light et let the other half go through so it can project on an other screen behind with the same projector. You can go up to two mosquito nets and one screen before loosing too much image quality.

Of course, the closer the screen is from the projector, the smaller the image will be so you cannot just have 3 screens the same size.

I have a pretty old picture of a video installation like this from the good old days

wow really. it's the same projection?
that was what was so interesting , the effect
adds a real 3 d quality to it
I guess I'm gonna have to buy some net and try it
thanks guys

Yeah go to a fabric store and check out their different meshes. Keep in mind more porous fabrics will pass through more light to more screens.
If you don't want to use premade frames (cost, weight) the biggest problem is keeping the fabric taut.
From experience bamboo makes a great top bar as its amazingly light and strong which means you can make it on site and get it up in the air by yourself. Also as bamboo so incredibly light you can hang it from almost anything.
As for keeping it taut, either another piece of bamboo at the bottom or fishing weights.

One thing though the fabric is a bastard to store and pack down so don't expect to get more than a few uses per screen before it looks manky and remake them.

Oh yeah and very contrasty content works best. Plain video works but content on a black background will look best and be like its floating in space.
