Inspired by quine computing, this is a nondeterministic ouroboros program that produces a random program that in turn produces another random program. Currently, at most 2^64 unique programs could be produced, but since the JVM allows for up to 65535 characters (including most unicode characters) in valid class names this could easily be increased.
