So satisfying. Do you think it's possible to take the end state of this simulation, reverse the velocities, and watch the 50 pendulums (pendula?) come together again, or do chaotic dynamics + floating point rounding errors make that impossible?

Not as satisfying ;-)

but to answer your question newtons equations of motion are invariant under time reversal, so yes it's totally possible
