gg zeno, gg.
my attempt at simulating super tasks in Scratch (which is impossible, of course) see: https://www.youtube.com/watch?v=ffUnNaQTfZE here we have a ball, that bounces at half the height of the previous bounce. thanks zeno. it also controls the lower box, with flashes on and off everytime the ball hits the ground. the high box simply flashes on and off and waits n between each flash, and every time it flashes n is divided by half. Once n = 0 it will stop. notice the list 'balls'. In this list, every step 10 balls are added and the first ball is removed. you can find the script in the stage. (iter is what ball to add) the orange squigly line forever moves half the distance he just moved, starting with half the distance of the race track.
