As an artist and musician, I often want to sit down and just let the code roll like a piece of free-form poetry, but I've found that doesn't work as well as when I have a set goal in mind. I've been experimenting lately with setting up tiny, fun goals for myself, not unlike how an artist would sketch a quick still-life, but I wonder...
What do others do when they want to code for fun, without the bondage of an already-committed project?
Design work, I find, flows much easier than just coding. I find that coding is often more of just implementation of a good design; I really like to just sit down with a pad of paper and a pen (and likely a bottle of wine) and work out an interesting design.
