Coding Challenge: Minkowski Sum to thicken convex polygons

I'd love to see how to implement a minkowski sum for a convex polygon and a circle so that you could thicken the polygon. Here's a [youtube link with a visual description of the result](https://www.youtube.com/watch?v=3qMNuoTHNHs). The reason that I came across this was I was trying to replicate the AMAZING work of [Jessica Rosenkrantz's N-E-R-V-O-U-S geode puzzles](https://n-e-r-v-o-u-s.com/blog/?p=7821). So you'd have to find the minkowski sum of a polygon, and then find the minkowski sum of the previous step ... .
