Giant Drawing Machines
Draw your body, hands and complex geometric shapes using giant drawing contraptions made from everyday materials.
Create complex Lissajous curves on paper with a Bicycle Harmonograph, big geometric flower shapes in sand with a Bicycle Spirograph and small Spirographs with bike cogs. Draw a miniature silhouette of your body or a poster-sized outline of your hand onto art paper using a Giant Pantograph.
Made from everyday materials, these contraptions demonstrate the magic of maths and mechanics in an exciting interactive way.
