Really stunning! I was impressed by the whole demo but one thing I wasn't expecting was the sample-based audio in the track played during the end titles. Another thing that I thought was impressive was the (pseudo?) 3D hills section.
Thanks! The 3D hills are no less 3D than any other 3D scene displayed on a 2D monitor. It's a heightmap (of a real place) rendered with correct perspective.
Getting the samples to output at the correct time during the end titles required a painstaking amount of cycle-counting, measuring, and iteration.
