The ultra-clean site of the Designmuseum in London, England is available in either Flash or Regular HTML. Designmuseum Flash features a great teaser gallery of pieces in their collection and on show through their Gallery3(cubed).
Some of the best parts of the site, aside from the great industrial designs showcased within, are the miniture loading animations between pages. The design style is also effectively translated into the navigational elements to create a cohesive content delivery vehicle.
