ON is a cdrom and a digital walk. The user can navigate through different environments using only the mouse.. The mouse is used only to indicate directions, clicking is useless. The different parts of the walk are abstract and are inhabited by 2D objects. Each object has its own behavior and sound. The movement of the cursor over the screen sets the world in motion. Some objects get excited when touched, other are a bit more shy and are startled when approached. (2001)
