The second series of "Experiments" that I uploaded today are a quite simple series of scenes based on using a large collection of flag images. There are scenes where the flags are used ase static or moving backdrops and scenes where they are used as screens through which you can see the performances - the example above is abnormal, most of the holes are much smaller and closer together and you can see all of the girl.
Other than the flags some of these scenes use a couple of shaders. One of the shaders is my own variation of the move2.vsh vertex shader which I have made a bit more flexible and controllable from the .scn file.
A second shader is one that can be used to punch holes in an image to create a screen though which performances can be seen. Again it is quite flexible allowing the spacing, arrangement, size, shape and orientation of the holes to be controlled from the .scn file.
I have thrown in a few scenes where the performers are only seen in silhouette before or behind a flag.
They can be obtained from via the Zips download page at TheEmusNest.eu or via the direct link

Although I posted this a couple of days ago its still the article in this thread so I can still edit it.
I had made a silly spelling error in the perforations shader and the scene files that use it, so I have corrected it and at the same time slightly increased the flexibility of the shader. The updated version has just been uploaded. If you did take the previous version please note that the new version of the shader is incompatible with the old scene files due to changes in the definition of the "uniform" variables used to communicate between them.
