Scalado's 'Remove' app for smartphones allows users to remove moving objects (read: people) in the background simply by clicking them after the photo's been taken. It works by taking multiple quick shots and being able to sub the background in one shot for the people in another. Unfortunately, the app won't be available for stand-alone purchase, but will be be included in phones manufactured by companies with direct licensing rights (currently Motorola, HTC and Sony).
