Exhuming the old pixel advertising methodology for the greater good, and working pro bono as well, creatives Derek Sherman and Dan Weeks--under the nom de guerre Middle Child--executed a website for Amnesty International USA that's a virtual online petition to tear down Guantanamo Bay.

Setting the notorious Cuban-based prison, and, more importantly, Capitol Hill, in its sights, Middle Child's mission is to collect 300,000 signatures for an online petition to undo Guantanamo. A bleak photo of prisoners greets visitors upon landing on the site, and by signing the petition, each participant receives a real pixel from said pic--300,000 in total. Once the target figure's reached, Amnesty International will have the numbers they need to effect change and every person who receives a unique pixel will be memorialized as their name is left behind and turned into a mural of concerned people.
