Am I missing something here? The rotate transform has been around for a while.
I'm guessing he's just showing off something he's working on, not necessarily re-inventing the wheel etc.
Looks like advertising for this specific camera, nothing else.
The products of the company I work as Frontend Developer are very suitable for preparing animations using HTML and CSS. I am developing projects and sharing them as open-source. Neither me nor my company does not have any advertising concerns.
What do you mean open-source? Nothing shown here is proprietary. It's a transform animated.
