London's Design Museum has announced the 90 shortlisted designs for its Designs of the Year 2013 award. Selected by a panel of nominators from around the world, the list includes the best projects from the last year across seven categories — Architecture, Digital, Fashion, Furniture, Graphics, Product and Transport —, which will be reunited in an exhibition opening 20 March. The overall winner will be announced in April.

Seeking to compile the most interesting designs, prototypes and designers in the world today, this year's shortlist includes such diverse projects as Renzo Piano's The Shard skyscraper, Heatherwick Studio's Olympic Cauldron, Louis Kahn's Four Freedoms Park, and Random International's Rain Room at the Barbican.

The nominations also include several prototypes, with a focus on socially conscious design — such as a fully foldable wheelchair by Vitamins Design —, while simultaneously keeping track of fundamental technological advancements — with such nominations as the new Makerbot Replicator 2, and Microsoft's Windows phone 8.

The full list of nominations can be seen at the Design Museum's website.
