Creative coding (still art and animations) combines these in a way, often people see something they like that someone else has done, and figure out how to recreate it in their language of choice, then put their own spin on it. Concepts range in technical complexity so it can be a great place to get started coding, there's no giant expectation of making a game or app.

On Dwitter (JS codegolfing/demoscene site) the philosophy is to make it as accessible as possible to remix someone's demo and post it. Even if not directly editing, one could reverse engineer the code to gain new understanding which can then be incorporated into the next effort
