ThreeJS rotating icosahedron with images on vertices

Jul 28, 2017

Simple clone of the Stripe element @ https://stripe.com/radar

I had some fun replicating the rotating icosahedron of the Stripe page, and in the end, it came out pretty good.

I know that on Stripe they have created their own solid using Cinema 4d.
