Nice idea. And well executed.

Nice!
good stuff.
What Virgill said.
Technical info. It's a two-pass shader, with pass 1 generating the "demo effects" into an offscreen texture buffer with feedback etc. and pass 2 doing a path tracer that utilizes the offscreen buffer. The path tracer calculates 100 rays per pixel, each ray with 1 randomly placed mid-air bounce towards the projector for the dust effect, and then a maximum of 4 regular wall bounces after that.
You can do this in Compofiller Studio with the settings like this
[x] Time uniform
[ ] Prev. fr. to texture
[x] 2nd pass
[x] Neg. time on 2nd pass
So when you do NOT activate "previous frame to texture", but you DO activate "second pass", then you have only the result of the first pass in the texture, and the result of the second pass only goes to the screen output, leaving the offscreen buffer untouched. Which makes the feedback rotozoomer possible. The second pass uses negative time instead of fixed 0, so that you can have independent action happening both in the offscreen texture buffer and the screen output.
The avant garde music was meant for a different kind of prod, and I started making one, but it ended up like this instead, and I didn't have enough time to make a new soundtrack for the visuals.

nice one!
Cool!
Cool idea!
ok, but there's been more intricate "projection mapping"-inspired 4Ks already sooo piggy
nice
Maali: post links so I can verify!
eerie. weak thumb =)
Enjoyable!
wow!
this was great! should've ranked higher imo
something about this kind of environment/lighting just always works :) also the dust effect is a neat trick!
ok
Very nice for me.
Nice!

if this prod is a fake, some info is false or the download link is broken,
do not post about it in the comments, it will get lost.
