LINKKI is a construction kit and STEAM learning tool for kinetic/robotic design. Its simple, modular and gender-neutral design lowers the entrance barrier to STEM learning and allows users to play and learn seamlessly across art and science. It has received many positive feedbacks internationally through a number of workshops and exhibitions, among others, at the Exploratorium(US) and Heureka science center (Finland), Helsinki Design Week, and schools and libraries in Finland. Most distinct of all, LINKKI provides not only a physical product but also the context of playful learning experience with accompanying guide materials and creative community around it.
