It won’t jump like that normally, I’m just constantly resetting it.

How does it work? Enter wireframe mode!

Firstly, a series of random y values are generated.

Next, a random angle is selected for the lower part

Then, we create the rest of the outline.

Finally, we have to thicken, and ‘color’ each segment of the bar.

And for fun, here’s a botched attempt at adding wobbles.

Considering the jam lasts a week, I spent far too long getting this to work.
