Megabrain Topographics, by Stefan Beckhusen:
The sound is made with Access Virus C. At the beginning and the end i included some samples which i made with my quite new Korg Kaoss Pad 3. The nature voices are from Atmosphere Deluxe.
The video of the Manta was fimed in Bali 2008 where i spend my last diving holidays.
