I love the idea of a visualization of overlapping language phonetics! something that showed both the hierarchical nesting of languages and the actual phonemes themselves. Besides tsu and dzu, every phoneme in Japanese is accounted for in the Spanish language. I believe that the Spanish phonemes are a nearly perfect subset of English phonemes.
