This 400 posts collection, 60 000 000 views, was as much a work of research popularization as a work of art. Google cannot be trusted with keeping high density data (scientific, art, etc). Read here about this.
It pained me to delete it, but it had to be done. It was harder than when I quit Facebook, Twitter.
The collection and richer material exist, I have them. Still, the Github repository is available, as well as the github.io demos. For example, the dodecahedron multiplication animation used as background for a conference site of statebox.io was made from a screencast of a d3.js which can be seen here.
