First off, to Unix Maximus, this app installs and runs just fine in Tiger. Umm, maybe you didn't read the "read me". Unlike most screen savers that prompt you where to put them, this one requires that you manually place it in your User>Library>Screen savers folder. I hate when people slam an app 'cause THEY can't seem to get it to work.
Anyhow,this is kinda like Solar Winds and nowhere as good as Helios. More of the same. Nothing new, but it works and the price is right.
