And please do not ask me if they'll work in this or that non-Photoshop program-- I honestly don't know, sorry!
Thanks for your suggestions and support, you guys are the best. Enjoy! :]
These brushes now have a GIMP download available; v2 download includes the GIMP files! BIG THANKYOU TO =HardLyUndead for putting them together!!

+ demo video
+ step by step image
+ GIMP files
First: Find your brush folder! Edit menu >> Preferences >> Folders (expand) >> Brushes. Click on the writable one (or make a new one to keep 'em separate). Copy the directory path to your file manager.
Second: Copy the files out of the ZIP file's GIMP directory to the brush folder.
Third: Restart GIMP!
