If I were into this sort of style I would hire whoever made these amazing cupcakes to decorate my house. Now find me some cupcakes that look like Le Corbusier and the Eames brothers designed them and I'll be in heaven.
I like a motif that combines snow with the color pink. It reminds me of a sunset on a snowy day when the vibrant sky reflects off the perfect whiteness. Throwing a couple penguins in there just ups the awesome factor.
