This is the classic/original projectM preset pack that was deployed with projectM applications until version 3.1.12. Newer releases will ship with the "Cream of the Crop" pack and others.
This repository does not contain the textures required by many presets. Please don't forget to also deploy the texture pack alongside the presets:
