Baris Eris has published an article on his blog detailing how he constructed a Lumia 900 compatible Windows Phone dock out of Lego. Yes, Lego. As one can see in the above photo, the device itself sits as one would expect in a dock and is plugged in via a cable which runs through the rear of the construction.
It's highly based on improvisation with the bricks available and should you wish to attempt to create your own Lego Windows Phone dock you'll need to invest in some packs of bricks to have the required variety.
Head on over to Eris' blog for more information and photos of his project. Be sure to let us know should you create your own.
