All credit for this given to Paddle2See. This one just has 8 dots instead of 4. Quotes from P2S below: "Watch the Perpetual Slinky that never gets tangled! Use the mouse to drag steps around to change the action. This project is just a simple visual effect. I was thinking about parabolic curves and I decided to make a project to demonstrate how handy they are for making trajectories. So if you want an object to be thrown from one location to another, a parabola is a good curve to use. Enjoy!"
