Major inventions and technical breakthroughs often happen by accident. Here legendary Apple co-founder Steve Wozniak explains how, while working with Steve Jobs to meet a deadline for Atari, he went four days without sleep. During a subsequent period of ‘zoning out’, his wandering mind began to consider and visualise replicating the colour bands, used in the colour televisions of the day, with binary code.

The result revolutionised the entire computing world.

Fascinating stuff and a valuable lesson in having more than one problem-solving methodology.
