Whale song art: dolphin calls turned into kaleidoscopic patterns using wavelets
These images may look like just pretty patterns, but they are visual representations of songs sung by whales and dolphins
The sounds were recorded by American engineer Mark Fischer and transformed into visuals using a mathematical tool called wavelets
Mark used to work on US Navy sonar and software for defence and aerospace companies but he now records the underwater conversations between whales and dolphins and transforms the waves into art
Mark then uses a branch of maths called wavelets which creates these intricate structures
