Fischer recorded calls from whales, dolphins and birds. The calls were transformed into wavelets, or spirograph-style designs. “The art comes from the sounds themselves,” Fischer told FastCo. “The images are simply wavelet transforms in polar coordinates. I do not apply any manipulation…”
What you are seeing is the visual representation of the myriad of sounds nature gives to us. The whales produce perhaps the most beautiful sounds (both auditory and visually) but the birds and dolphins do create some interesting pictures.
