Professor Fletcher’s invention of the CellScope, which is a Nokia device with a microscope attachment, was the inspiration for a teeny-tiny film created by Sumo Science at Aardman. It stars a 9mm girl called Dot as she struggles through a microscopic world. All the minuscule detail was shot using CellScope technology and a Nokia N8, with its 12 megapixel camera and Carl Zeiss optics.
