This makes me feel old. I saw it for the first time in 2014 on HN, just when it was announced. I felt kind of envious of Kevin Kwok, author of this project. I had just graduated and he was still an undergrad. He had already shipped so many complex projects, including a full-fledged Flash Animator[1] for the web.
It's pretty surprising to see that his site hasn't been updated since 2015 and not many projects have been shipped since then.
