Oooh, I didn't know that technique was called vowel space rendering. I love the look of it, but, more importantly, it seems like a fairly trivial way to encode multidimensional information and make it navigable by humans. (I'm having loose ideas for e.g. representing the health state of software systems this way, letting the operators "fly" around and get an intuition for what things are like. Coupled with sound it could get fairly immersive.
