I tried making a pendulum/rope thing. It attaches to your cursor and you can move it around. Hold space it have it detached from your cursor.

It’s not perfect – for example, the pendulum loses energy when swinging even though I never programmed that in. And when you have a longer rope, the force of slightest movement amplifies as it propagates down the rope. These problems are probably caused by the fact that I don’t know how to properly apply the tension force, since I don’t have a lot of physics expertise.
