Music made by your brainwaves

If your thoughts could power music, what sound would they make?

The BBC met programmer Adam Williams who, along with team members Robert Wollner and Alex Wakeman, created a program which uses a brainwave-sensing headset to power a musical composition.

The Soul Filter was on show at Art Hack, an event organised by 3beards, a company which specialises in organising gatherings of east London's start-up community.

Mr Williams' father offered up his brainwaves to give the technology a try.
