Experiment, breaking up a drawing of a kettle with a soundwave patterns. It ended up giving the image a sort of Dali, surrealist melted look, which was an unexpected outcome.
Might try taking a photo and emulating the soundwave pattern by moving the imagine in a scanner to manipulate the image. Especially as this would look perhaps more scientific, like a frequency diagram of sound.
Brilliant experience exhibiting among so much amazing art, would highly recommend going to the next exhib, which I think the organisers hope to put to together around the end of this year! Logistics meant that I had to go for a footlight instead of a spotlight, BUT the overall effect remains the same I think.
