I am very impressed with the hidden gems of stripe's landing page. Here's[1] a post I wrote that analyzed the drop down animation they use. I've never seen it anywhere else.
in the early aughts I remember "mega" menu's were all the rage. Most have been abandoned because they were too hard to make responsive. Cool to see stripe went for it utilizing some pretty interesting CSS properties. It's cool they were able to keep it responsive down to 670px.
I also liked your analysis of how the perspective property worked in this case.
