Acoustic Diffusers Echo

This is a "not good for anything really" video that tries to represent the acoustic wave-front reflected off varios diffusers versus a flat plane. Not taking the video very seriously, schroeder diffusers seem to no differ too much between having or not having well walls, but they do differ slightly. The 2d modulated version of the diffuser looks a lot cooler. The frequency response and polar patterns (which are very important) are not evident at all when looking at these videos.

It's a nice graphic. But unfortunately it doesn't show how diffusers work. ;)
Sound doesn't bounce around like balls. It travels in waves and the interaction of these different waves that are bouncing off the structure make up the diffusion.

Thanks for watching my video.
Yes, you're right, and I know. But just as the description started off, it's a no good for anything video, just for fun. I used a program that's not intended for acoustics simulations either. Acoustic diffusers work by interference between the incoming soundwave and the reflected one, obviously not what you see in the video.
Anyhow, the simulation method I used could in fact work. Air is made of molecules which could be represented by the little particles in my simulation, only that they are pretty much stationary in space and wobble around with pressure perturbances. The problem is that the software I used might be capable of doing it, but the ammount of ram needed would be a bit too high. I did try but it kept crashing, so I did what I did instead. It was quite amusing though.

This animation works perfectly to show the time delays and the scattering of very high frequencies. You're right that it doesn't show diffusion, though.

What software did you use ?
