VT's "Download Now" link took me to the page "http://my-webs.org/blog" where I kept getting a 404 error. If, however, you use the "Developers Site" link, you can go to their site and download it from there.

Also, please note that this is a Quartz-based screensaver, with extension .qtz, and will not work in older Macs, not even early G4's, which don't have a Quartz Composer compatible graphics card.

I don't know why, but this developer is distributing this 12K file as an OS X package, (as opposed to a simple .zip, .sit or .dmg file), which installs the screensaver globally for all users in HD/Library/Screensavers, and not in your home folder's "Screensavers" folder.

I can't comment on the functionality of the software, as it won't run on my G4 DP.
