Gosper Curve Coaster

I wanted a coaster that didn't let a vacuum form under the glass because of condensation, that way it doesn't lift the coaster all the time.

A naive solution is to just use some straight ridges but this means that small glasses can be easier to tip. Lots of bumps have this same problem because they create cliffs.

So I wanted a coaster that didn't make long straight cliffs, the Gosper Curve makes a great way to do that.
