Over time I have regulated the typical movements, and modified them into other actions that may not be so perceptible. I adapted my penguin flapping, to shaking my hands, to fanning with my hands or interlocking fingers (hard to describe) - moving hands back and forth. Rocking, swaying and swinging, still endeavour to minimize this, although with head phones these days, it isn't so unordinary. Have converted some movements to shoulder shrugging, and turning my head to the right, although I am not averse to leaving the room if need be. Listening to the same song, and watching the same movie incessantly is still something I do. Observing intently things such as running water, fans and the like, I still do.
