Lewis (named after Meriwether Lewis) is an autonomous robot that performs the job of a wedding photographer: it attends social events, moves around, and takes digital photographs of people. It is a research project of the Media and Machines Laboratory at Washington University. Lewis has been featured on slashdot, on CNN's website, and in various North American newspapers. In 2002, Lewis received -- and declined -- an invitation to Nelly's 24th birthday party.
