Your typical Kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other in an angle, so that objects on one end of the mirrors are seen as a regular symmetrical pattern. The reflectors are usually enclosed in a tube, containing on one end loose coloured pieces of glass/plastic or other combinations of transparent and opaque materials to be viewed. Rotation causes materials to move creating random patterns. This version closely follows the general design however, were your typical Kaleidoscope uses physical elements that move under the influence of movement this version used LED's to display everchanging random patterns. The patterns are displayed on a Zip tile this contains 64 LED's in an 8 x 8 matrix which are controlled by the Microbit.
