I was actually thinking about implementing exactly this (using feDisplacementMap), but never found time and I was not sure if it would be possible at all. Great to see that it actually works and someone with deep SVG knowledge implemented it. The whole blog entry is a piece of art and on one level with Bartosz Ciechanowski's work. If you want to make money from it, you will have to find less niche subject's, though.
