After many months of working with Jon Lech Johansen (known on the internet as ‘DVD Jon’) and the other guys of the doubleTwist crew, I’m proud to announce doubleTwist for Mac has gone public today. I’ve designed doubleTwist’s icon, website, logo, and the interface together with Sean Patrick O’Brien.

doubleTwist is a great application (soon also on Windows) that aims to be for media what the browser is for the web. Got some music in iTunes and videos on Youtube you want to put on your Blackberry, or PSP? No problem, doubleTwist will handle all the details. Want to put your elaborate photo album of your last vacation on flickr, and share a select few privately with friends? doubleTwist does it.

It’s really an amazing idea for an application; you’d start to wonder why such a thing hasn’t been done before. It’s all very simple and fun to use. I suggest you check out the nice screencasts on the doubleTwist website, and download the beta. You can also see if your device works with doubleTwist.
