The color information of the wood sample images are translated from the spatial domain into the frequency domain by applying a Fast Fourier Transformation (FFT). Regularly reappearing features of the image are captured and described by their wave length, amplitude, and phase angle.
By crossing over high and low frequencies from different inputs, by flipping rows to create new symmetry relationships or by applying filters, new and somewhat intriguing kinds of meta-wood are being synthesized following a hidden musical score. The results are not just mirrored but interwoven, not perfectly symmetrical but a bit like a piece of wood cut open and the two halves put side by side – similar but not equal.
