‘Multiple Seismic Waves [first version]’ [2016] by Matt The Unfathomable Artist, Blue ink on A4 paper, artwork whereabouts unknown.
I might like to varnish some or all of my sketches.
My second version of the ‘Multiple Seismic Waves’ series includes varying frequency waves, as follows:
One full page seismic wave centrally placed. Twenty three clearly visible smaller seismic waves. Finally, there are also some lovely lightly penciled full page high amplitude, oscillation styled, long wavelength patterns too.
