I'll go with this theory as well. Anyone have google glass and an augmented reality app from google? That login logo seems like an AR trigger waiting for someone to look at it the right way.

also found the rhgame reference in css...

Yeah, that image looks like it was designed for easy recognition. Picture search via Google Goggles doesn't return any results, though.

SVG sources gave nothing obvious. Unless they encoded data into path coordinates and/or colours.

it very well could the name of the css file is rhgame.e6cf5ce7.css <-- "RH GAME"
