Lightbulb is a digital artwork created by Michael Craig-Martin for the Serpentine Galleries Galleries on the occasion of his exhibition Transience. It is a drawing with six coloured elements, controlled by a software algorithm.

The image changes continuously, with each element of the drawing fading between the 47 colours in Craig-Martin’s palette. Several hundred colour steps take place during each fading process and there are millions of potential combinations.
