A while ago, I built a new tab page using Enyo at a Facebook hackathon. I never got around to posting about it here. Its based on a concept by a friend of mine, and built with a mix of jQuery and Enyo. It also uses a neat trick to automatically determine the primary color of website icons. It's not the most useful new tab page, but it is sort of neat.
You can get it from the Chrome Web Store at the link below. Let me know what you think!Get A New, New Tab Page!
