Click and drag to draw a curve, then drag the slider around and watch it slide down the curve! With math, you could keep shortening the length of the slider and get the instantaneous rate of change at that point, but it wouldn't work with Scratch since it needs two points... :)
This is kind of a boring project, but I've been trying to simulate this for a long time. It's still far from perfect, but it's the closest I've gotten to making something slide down a curve. :) Also, I'm using a sprite other than just pen for the first time in a while!
