Synesthesia is a condition in which one sense (for example, hearing) is simultaneously perceived as if by one or more additional senses such as sight. In this workshop, we will introduce Synesthesia and give a small example of it and where it is used. After that, we will start building a small electronic circuit that will produce music during the usage of the pencil, and involve the human body as a part of the circuit. The implementation is user-friendly, and no soldering needed. Therefore it is an excellent workshop for children and adults. We can't wait for your creativity and excitement.
