Rain Campaign

raincampaign.com is the home of the newest ad media, ads that reveal a hidden message when rained upon. In keeping with the name, they give a portion of money advertisers spend with them to support the rain forests.

The only snag I see with this media is that when it rains most people are usually trying to find cover as soon as possible, therefore ignoring rain campaigns. But I could be wrong, what do you think?
