52.5 mins render, one light source, three df3 files to absorb
light, a white box to project upon, and a scattering media.
Now just need to make the rest of the scene.  And maybe run
a df3 of a movie of some sort through an animation...hahahah

Simple but nice efeect imho, and good choiceo of example frame.

Btw, why df3 files? 
Wouldn't it be more simple to create just a box (or rather 
4 point polygon/mesh giving a flat box)  +scattering +light +white_box ?

um...um...

hmm ok i guess an image pattern of the channels colour
mapped to each channel and filtering 100% of the light
at one end of the greyscale and used as a flat texture
would work too...

but why df3 files is because i originally used the
technique as a simulation of a CRT, with emitting media.
i thought to myself, "self, what if you made that media
*absorbing* media and shot light through a negative-colour
version of that?".  ergo, this image.  ^_^

Except I just tried it and it doesn't work.

That's pretty cool!  I've thought about doing something like that myself,
but I've never actually tried it.

But wouldn't this also be possible with a normal image map with "transmit
1"?  I remember when I was messing around with my butterfly, that I turned
on something like that, and the wings projected onto the ground.

You need filter instead of transmit
