🍍↩️ Pineapple Placement, Part 1 | Complex Web Animation Challenge! | @keyframers 2.8.0

David Khourshid (invisible and inaudible) and Stephen Shaw build a complex web animation based on a Twitter challenge by Josh Comeau. We'll return for a part two with David visible and audible 😬

(Note: David's audio did not come through properly due to a technical error on Shaw's part. Oops! The episode still has lots of good bits, but starts out with Keyflections with a little dubbing that help explain a bit)
