A great campaign run by Garbergs for Stadsmission - a small charity in Stockholm dedicated to helping the homeless. The campaign was based around plain black banners with no website to live on.
On the microsite, users were encouraged to pick a banner and give it a home by embedding the code into their own website or blog. The banner became brighter the longer it was hosted and the more people clicked on it.
The campaign was launched through facebook and twitter and with over 400 websites hosting homeless banners and 36m impressions, donations tripled.
