IGN recently released a new website cataloging the history of Mario. Starting with his early roots in the game Donkey Kong, IGN new site is an fun jaunt down memory lane. IGN parented with HTML5HUB to create the Museum of Mario entirely in HTML5, so if you are flash adverse this is your jam.

Speaking of doing awesome things in HTML5 with Mario someone recently recreated Super Mario Brothers in HTML5 and released it as Open Source on Github. You can play each level from the original game and also play a special random world mode where each level is procedurally generated. Check it out.
