Abstract: A gaming concept in which each user in a single-player or a multi-player game is enabled to create artwork or graffiti work virtually or on actual surfaces using haptic-enhanced controllers. The controllers can emulate the experience of using a marker, a paint brush, a paint spray-can or the like.
