Very nicely done and quite enjoyable. I like the mandlebox because of the "structure" one can find in it, a personal thing for me. The soundtrack was pretty nice especially the opening piece and the song around 14:00.

The rendering is first class. My only criticism is that I felt the camera velocity could have been a tad bit faster in a couple places where the structural detail wasn't that complex.

Thanks for sharing. Cheers.

I don't know the exact parameters, but here you can find the FRACT file with all canged params:
