Very cool! Well done! My only suggestion would be to replace the font used for the letters with something more generic. As it is now, some of the letters don't really look the way they usually do in popular fonts. I think the best examples of this are the "G", "Q", and "S". The "G" actually looks better in Firefox 44 than Chrome 48 (both on Mac OS X 10.10). I like the animations, though, and I like how the letters animate when you hover over them.
