Simon Henwood directed and Phil Tidy produced this video for Imogen Heap's Propeller Seeds - aka Heapsong 2, a '3D audio' song that she created with Nick Ryan - and her fans.

Simon and Phil shot the video in Imogen's back garden, which took place before the track was completed, with the atmosphere inside the balloons recorded and mixed into the music.

Fans were invited to submit their ideas about being in their own bubbles; six ideas were chosen which Simon absorbed into the creative - and those six fans were also invited to appear in the shoot, one even flying in from the US.
