This was a rather quick (2 weeks) UI demo I whipped up as a "test of capabilities" when I was interviewing for a position at Cloud Imperium Games, the company responsible for the highly anticipated Star Citizen
It is built entirely in HTML5/CSS/JS, but might not work on some devices as well as IE8 or lower (not enough time for compatibility testing!).
Basically, this is supposed to be a ship catalogue viewer to display each ship's hardpoints, specs, upgrade capabilities, etc. in a full-screen FUI/OS'ish style interface. You can rotate / flip the ship to see all angles and where everything is located. A more polished version would have a dropdown to switch to another ship, but I was only required to display the Hornet.
