I thought about something similar a while back (in a different langauge with a compiler). I don't think you really need batch files and projects, you can do just fine with a "clone" vi.
A slight modification to your premis means that you can "grow" more and more complex "creatrures" and see evolution (in theory at least).
Rather than "spawn" the children and hope that one of them may survive, you can use your DNA program (Prime Mover?) to create a vi that has the DNA code + 1 random function. It continues to do that UNTIL something compiles and runs. Now you have DNA and DNA+1 in the primeordial computer soup and each continues to try and create a better "self" until it runs out of functions to try. At which point it becomes "Extinct".
Of course. If nothing compiles and runs then it proves you are a crap God
And, by the way, we all know the answer for a computer is not 42......it 10
