We've added a collection of HTML5 based games to the web site under the "fun" section in the main navigation. The reasoning behind this is twofold, one yes they are pretty fun and pretty impressive but realistically point two is that they showcase the raw power of HTML5, something we strongly believe in.
Take some time and check them out, we will probably be adding more shortly also. We've enabled the five heart ranking system on these page also so if you like them be sure to rank them and let others know.
Personally, I got a bit too addicted to Hex FRVR too quickly. ;-)
Update 1/1/16 - We've enabled a score keeping system on the above Hex FRVR page, to allow you to capture a screen shot and brag about your score and challenge others to beat it if you so desire. Note: The comments do not go live after post but all will be approved which are appropriate.
