3D for All Ltd’s multi- patented development Leonar3Do complements an ordinary PC into a 3D virtual reality system that can be easily accessible by anyone. The user – even a 10-12-year-old – can create his or her own virtual world in the space in front of the monitor: s/he can draw in space, create models and patterns, invent toys, make and play games, build structures out of predefined shapes, and much more, all carried out in a way that earlier could only be dreamed of in a science-fiction world.
