Same. Reminds me of when I was a child playing videogames. I knew that animation was a series of still pictures, so I assumed every possible image the game could show had to be pre-rendered and shown at the right time, which is exactly what's been done here!
Very interesting. It reminds me of template metaprogramming in C++ as (assuming you generated this, and didn't write it by hand) the computations were completed at compile time!
