Putting it in ~/library/screensavers manually really is a minor thing. Tip: If you really want a special treat and have a screensaver hardly anyone in the Occident has go to the developer's website and download Odyssey For Boys And Girls Screensaver. It is GREAT! It is in japanese with English titles and works great in 10.4.5 It is NOT available on VT. The screensaver is along the style of the developer's 20th Century and Full Color Bossa. It rocks!
