What is the purpose? I don't have a clue how to do it but I'm curious as to
why someone would do this.

Water features, landscaping, etc. Boulders are expensive too purchase,
but faux rocks are easy to make. The ones I've seen constructed were
made with 3/8" galvanized mesh. Shaped to size...

Once you have the shape, then a three coat of stucco/motar.

Samples like used in the desert: (photo gallery).
