A 3d rendering of your creation into some video rendering program would be fascinating. It obviously would take alot of computing power but you'd be able to render an entire video of one's voyage through a dungeon and later ad the colors and contrasts. You wouldn't even have to make it look realistic, just leave the paint effect as is here. But that would definitely be alot more work than it sounds in my suggestion.
(still fascinating though-this reminds me of someone's passage through the mines of moria from LOTR)
