brief: increase subscriptions to creative review.
idea: reading creative review increases your creativity.
execution: manufacture (and sell online) a USB device that tests your brain activity.
a microsite would house all the creative review content alongside other random stuff (monkey porn, holiday photo slide-shows, kettles boiling etc) and you can see how different things affect your brain activity.
advertising:
recruit well-known creatives/designers/animators etc to test the brain activity tester, and show their results online.
