Very interesting! Reminds me a bit of ladder logic, a 2D visual programming paradigm based on wiring together relays - but at a higher level of abstraction, since ladder logic is mostly based on simple boolean operations and doesn't really have any notion of defining functions. The fractal tree and UTM examples are absolutely beautiful and mind-bogglingly simple.
