Hey @anil, thanks for the super thoughtful comment :)
That filming setup was super ad-hoc one evening, as we filmed it at home and I brought back just two GoPros back from my office to shoot with.
(The overhead bar is a mop handle propped up by the clothes horse haha)
It's the first time I've used a smiley on my kids faces - usually, I do the same, with shots from the back or close-up's of the activity in mind - but this struck me as a good way of keeping his identity private but also letting people see the full context of what were doing.

Sharing and privacy is such a bigger concern than it probably was to most people only 5 years ago.
