ATOLLO is a dynamic and creative construction toy system, that allows you to build flexible models. The original ATOLLO prototype was invented almost 20 years ago, as a tool for studying structure by Donald Macdonald in Edinburgh, Scotland. Since then Donald & Euan Macdonald, designers of the ATOLLO System, have transformed the original prototype into an amazing and dynamic system. ATOLLO is intended to be a fun and educational experience, allowing you to create amazing and flexible models limited only by your imagination !
