I submitted some hills that
this bot generated to an art contest a few months back. Three of them were chosen — for the high honor of being made into murals in some condo in Pennsylvania. I was recently asked to provide them as SVGs for production.
It was relatively easy to do for one of them, but the other two were generated before that bot used seeds to make its random choices. So, in addition to testing, this is another reason to seed your random number generator.
