Andy Rubin Android K version

Dunno how we all missed this during Google IO -- but we did. There in the demonstration of how you can resize widgets is either a fun little Easter egg, or a very excited Andy Rubin, who on May 6 apparently sent an e-mail with the following subject line:

K release — I've got the BEST name ever ...

Now all we have to do is figure out just what ol' Andy came up with. Any ideas?

Thanks, Brodie!
