Geek chic.

Those Lego accessories spotted on the Marc Jacobs runway are both easy and affordable to recreate.  Snap a few blocks together, glue a paperclip on the back, and slip the charm onto a pendant chain.  Or, try gluing the plastic blocks onto the back of a pin for an instant brooch or onto a plastic headband.
