To me it's way more interesting than TFA, as it's really not obvious why the wheels would work, and the wheels don't work "out of the box" either, you can't just slap wheels on a tuned "static" trebuchet and need to do some re-tuning to get the correct synchronisation between the arm and counterweight.

Really neat.
