"Animated Bokeh" has been on my whiteboard for a long time, and this is the result.

I thought it would just be for cheesy novelty effects, but it also does lightfield manipulation that was cooler than I expected.

@ancientjames I love that you do this, but I hate that you make it look so easy, but I love that, because you make it look so easy, I feel encouraged to give it a try.
@flipper I really want people watching my videos to see that these things can be done by one person, quite cheaply, at home. I always try to include some of the missteps and experiments along the way, but I always end up cutting those bits because they make it hard to follow what's actually going on. The result is a video that makes it seem as though I knew from the start what I was doing and how to do it, but the reality is a lot more haphazard and meandering.
@ancientjames @flipper

On the off chance you didn't try: would partitioning everything into "main flow" and "failed sidepath" and indicating failed sidepath with a colored border or something make things easier to follow?
