Ready to be used as inspiration for your next design and mechanical challenges, not only in the traditional watch industry.

To Theo Jansen’s Living Mechanisms

As our beloved Form Follows Function approach, Theo Jansen has brilliantly applied shape and simple principles (the principle is simple, and the application is extremely smart and complex). But let’s have the kinetics principles of his walkers explained first:
