Edit: reading is hard -- I only skimmed and did not realize she was mentioned.

We love engineer Kala. She decided to do a thing, while marking progress on her "technology tree" of skills gained by (very arguable) necessity. Dealing with permits and city beuaracracy seems like one of the hardest parts!

That was a big part of Christo's art.

He explicitly mentions her in the video.

My bad, I just skimmed. This is HN after all ;-)
