Potato built the online campaign for Amnesty International's Secret Policeman's Ball for Mother.
Celebrating fifty years of the charity's campaign for free speech, spring 2012 will see see stars including Coldplay, Jon Stewart, Stephen Colbert, Mumford & Sons and Russell Brand, gather in New York for a huge Secret Policeman's Ball comedy show.
A Facebook app was launched as part of this initiative, housing a competition and YouTube-powered video auditions - with the public able to vote on their favourite videos, giving one lucky comedian the chance to appear at the event.
The campaign was built to designs implemented by Toaster, including the main campaign website secretpoliceman.com.
I had a lot of fun working with Potato on the Secret Policeman's Ball. They worked hard to deliver the Facebook app and campaign hub quickly and to a high-standard, vital for such a high-profile, public-facing campaign. I hope to work with them again.Peter Hadden, Mother London
I'm very glad to win the 15 seconds at the Secret Policeman's Ball. Dragons love New York, although New Yorker's seem to have a bad opinion of dragons ever since that whole Godzilla episode in 1998. Plus, it'll be nice to be by the sea again. I used to live there, but I moved due to lack of work.
Russell Brand, Coldplay and a host of other acts have taken part in a Secret Policeman's Ball gala in New York - the first to take place outside the UK. The Amnesty International benefit at Radio City Music Hall was held to mark the organisation's 50th anniversary.
