Take a walk on Planet ETH. Starting in the desert lands created around 2015. Some say the desert contains the rarest plants .... Or go to early 2018 where you can see lush plants fueld by large eth transactions. Each transaction is a seed that starts to grow from 1ETH. The transaction hash is the blueprint for the shape and distribution of the plant's properties. The latter is determined by the plant's DNA that is generated from the block number and timestamp (this will be included as trait). Land & sky are created on the curves of the block hash. Have fun and go explore!
