These brushes are for Photoshop, and the above video will explain the setup and format of the brushes, which need to display as large thumbnails, with 9 brushes per row.
They are a combination of brushes I've made myself and those culled from friends, colleagues, and other great artists. A lot of them might have bizarre names, but they're all categorized so it shouldn't be a problem.
Enjoy, and I hope it helps!
