The way that the iPhone’s display switches from portrait to landscape mode automatically is a really great feature.
It would seem then pretty obvious that any dock should let you do the same thing having said that they don’t most of them are fixed in a vertical portrait mode.
This dock made by Steven Combs is really cool not only does it let you rotate your iPhone it also has a high tech look made totally from Gray, Black and White Lego parts. We know that there are a few commercially available rotating docks out there but why not just have a go at copying Steven’s idea and make your own. Source - dvice.com
