I started working on InstantView years ago responding to someone on Reddit asking if there was an alternative to the Chrome extension "FasTube". Since then it's gone through several redesigns, rewrites, and feature changes. I also began using it to test out some fun audio visualizations that can be used on any YouTube video (that doesn't disable embedding).
