The website graphics and various accessories were designed by Justin Gammon with some help from Dan Heath regarding slogans. The photos displayed were sent in by the people who are shown on them, with two exceptions: we thank Wojciech Dorosz for the wide photo of people from developing countries, Derek Goodwin for the photo of Peter Singer. The video came from the collaborative work of Jeff Sims (visuals), David Hamburger (music) and Dan Heath (script). The text content was prepared by Peter Singer. Brains on Fire provided some ideas. The contributions of Justin Gammon and Brains on Fire were made possible through the involvement of Dan Heath, while programming work was financially supported by Peter Singer. Programming was done by Arnikowska Studio and Pawel Arnikowski.
