Sketch Town is a town that grows and evolves according to the pictures drawn by children. After the 2-D drawings of the cars, buildings, UFOs, and spaceships are completed, they are scanned, become 3-D and enter a virtual 3-D townscape. Every component of the town has a role to play; for example, the fire trucks and cranes serve to protect the town. Children can interact with the final townscape by touching individual components to alter their behavior.
