Eufloria HD for iPad is out today.
I was in the beta test team and can tell you, it’s one of the most beautiful and amazing games I’ve ever played on any operating system (and I’ve played a lot!).
I’ve played it for two years on Windows (also on Steam), it’s also available for PSN, will be available for OS X and iPhone some time in the future.

(German App Store link, don’t know whether you’ll automatically be redirected to the store in your region. Also, it may be that it’s not available in your region before midnight.)
