Audacity might be a free sound-editing program, but it can also be used to create glitchy, psychedelic image manipulations. University student Jamie Boulton has documented the bizarre effects that can be achieved, while simultaneously providing instructions on how to generate similar results at home. It's fascinating to see what happens to an image after its non-existent bass has been boosted or when it is subjected to a pitch change. Boulton even shares a method for creating eye-melting GIFs, which resemble a hallucinogenic nightmare. Be sure to check out the other links on Boulton's page to learn more about what he calls "databending."
