*Edit Reason: Update*)
I saw a picture of a ripple tank and thought Hey, what if...?

Turns out there's an old, really simple algorithm to simulate ripples. I hacked together a quick program in C++ to run the algorithm at a ludicrous resolution. After it seemed to work, I ran the algorithm for 200000 frames at a resolution of 1920*1200. I ended up with a not-completely-horrible hall reverb impulse response.

The impulse is pseudo-true stereo, with the left and right impulses being the same, only with swapped left and right channels. It actually ended up like that by mistake, as I had no randomisation active in the program and the source and pickup positions were symmetrical for left and right in a rectangular room.

While I'm by no means aiming to develop the next Impulse Modeler, I'll probably continue this experiment to see how much it's possible to improve the sound.

I've attached the impulse response I ended up with, if you'd like to try it out.

Update:

Artificial Hall - test 2

This is another experimental impulse response, done using a different (and considerably faster) algorithm. This one is in proper true stereo. A short demo is included.
