I just found Polyvore.com (should also be known as “Playground for Collage Fiends.”) I am in love with this site for so many reasons … the color and image choices (not to mention fonts and music!!!) and the entire freedom to combine them; the fashion ideas; the sheer talent of the guys who built this software to be so user friendly (and fun!); the community aspect; and mostly, the marketing genius of allowing any user to create beautiful palettes of purchasable items and then pushing them forward in a viral marketing effect. Brilliant.
For some background information about this site, see this article from The New York Times.
Here’s my first collage — of many, I’m sure. So sure, in fact, I’m adding a section for them to my sidebar. Have a few minutes? GO PLAY!
