Gather, is a digital agency based in Manchester in the North West of the United Kingdom. Incorporated in 2012 after a successful collaboration brought together creative energy with sound strategic thinking. The installation will be a photo booth style experience with a touch screen enabled device and camera (iPad) which allows users to take photos of themselves (and others) with overlayed charicature features. The charicature features (Christmas themed) will add elements to a persons face (hat, ears, beard etc) in a Snapchat filter style to turn the user into a character (Elf, Santa, Raindeer). We see this working very much like Snapchat, where users apply a filter to their face before capturing it as a photo.
