Master thesis project @Aalto University School of Arts, Design and Architecture. Linkki is a kinetic construction toy based on planar linkage mechanism with which users can design movements, make kinetic arts and learn basic STEM(Science, Technology, Engineering, and Mathematics) subjects by hands-on playing. Consisting of a modular box, bars and circles, and active modules, Linkki simplifies the technical construction toy to such an extent as to look minimal but still retains the versatility of construction blocks as an educational tool and designer’s prototyping tool. ©Eun Young Park 2015
