A couple of days ago I received the email with the rules for the #codepenchallenge. I started writing the demo for it, but it was getting bigger and bigger. So I pushed it to GitHub repo instead. This is a WebGL globe with points for all earthquakes with magnitude more than 5 which happened last year. The live demo is here. This is an alpha version, so I recommend to use Google Chrome.
Simple UI framework. RSCSS, REM-based sizes, fluid typography and other nice ideas. This website is powered by it.
