Love it, simple and smooth even on my lowly G4 eMac 800 with a measly 256 MB's while running multiple applications on OSX 10.4.8 !
Only minor issue was the installer, instead of placing the screen saver in my /library/screen saver folder, it created a new user called Cory something and added to it's screen saver folder.
For me manual installation was the only way to go!
Keep up the great work Cory, minor bug and I still love!
