The ask was to create a website that would look and animate like they did in the Flash days. The entire site is built into a HTML Canvas. There were animation libraries such as PixiJS and CreateJS but they lacked the speed and specific graphic abilities needed. So I built a custom render system for all the animations and interactions. This made it extremely smooth and fast, and would even animate well on an iPhone 1. The 5K transparent images are precompiled from a JPG and a black and white PNG image (to save on image file size) by using available CPU calculation time while the site is loading. It was meant to be a temporary site but stayed up longer than expected.
