William Burroughs, author of Naked Lunch, famously used mechanical means to spark his creativity. He and Bryon Gysin were the first to use the “cut up” method in literature. They had various methods for cutting up pages of text and rearranging them to create something new. They by taking the text apart and reassembling it randomly, you could reveal the real meaning behind it and create associations you would have never come up with. Languageisavirus has a tremendous number of these methods automated and available for you to experiment with.
Burroughs and Gysin also experimented with a flickering Dreamachine that sparked hallucinations in some and seizures in other. It has worked for me, try to see if you find it useful. Don’t use it if you are prone to photosensitive epilepsy.
