(I've been watching the other half mowing down splicers in Bioshock all week, so I reckon I'm entitled to go a bit girly for a moment.)
I came across this fantastic site Polyvore yesterday, via this story on Valleywag.
Polyvore lets you build really quite lovely fashion-mag-style page layouts (or 'sets') out of pictures and patterns sourced from all over the internet, including online retailers, royalty-free stock photos, Flickr images and more.
The site says you can use it to see how clothes and accessories from different shops might look together, or to try out new interior décor themes. Me, I think it'll provide hours of unadulterated pleasure for anyone who reckons they could easily have been the art editor of Vogue or Elle Decoration, if only they'd managed to get the hang of Photoshop.
Here are a couple of examples of user-created 'sets':
Pretty, eh? You can browse more here, and start making your own sets here.
And it's Web 2.0'd up to the eyeballs, of course, so you can also upload your own images, comment and vote on other people's sets, embed sets in your own blog, tag images and sets, and make new friends in the Polyvore community.
