RenyiTong is a set of DIY connectors that can be assembled to create different models and objects. Every component can be directly connected with another or linked through wooden sticks in round or square forms to achieve more creative variations. Models such as toys, daily utilities, creative designs and device production can be made with ease. Just a few connections allows one to rapidly form connections, points, lines and surfaces in three-dimensional space. RenyiTong helps users understand and develop three-dimensional creative insights in an effective way.
