If you have a phone with a pen (e.g., Galaxy Note), sketching is rather fun. FWIW, I use Adobe Sketch, for which I get a license through work. Not quite creating but also not quite passive consuming: Anki or other apps for learning (when I am in a good period, downtime becomes opportunities for buffing up geography and music).
