I'm struggling to understand how this works. Where have you got the function input from? Amazingly realistic!
u/Jenky

It's from (u+'') - afaik, it's basically a short/cheat way of converting anything to a string in JS :D

Some nice math for the 270 initial radius: The half-height is 540, this must equal r+r/2+r/4+r/8+...=r(1+1/2+1/4+1/8+...). Think about the bit in the brackets in terms of pizzas. You have a whole pizza, plus half a pizza, plus a quarter (half the remaining half), plus an eighth (half the remaining), etc. You have two pizzas! So 540=r*2.
