Well this is interesting - Google bought the guys responsible for BumpTop, the very slick 3 dimensional desktop application. I have always been a fan of the idea of Bumptop, but I hated running another layer over my background. The few times that I did test it I was always impressed, and it ran well, especially its recent Mac OSX version. It was however limited in its free form, and hopefully Google fixes this. Just like Picasa was little known before Google bought it, maybe they will set Bumptop free for all OS's, with quick links to all Google services. I can imagine that being very handy.
Please Google, dont keep Bumptop only for your upcoming ChromeOS (or Android).
Set it free.
