1. The document discusses CAPTOY, a building toy system that uses round studs allowing blocks to connect in any direction. It has applications for mosaics, 3D building, and creating structures from the side or top. 2. CAPTOY aims to be a "one-block building system" using a single tooling and molding process without additional parts. This allows for 24/7 production with no waste. 3.
