Unsanity LLC releases WindowShade X
WindowShade X brings the familiar window-collapsing effect from MacOS 9 into MacOS X, and more. Stacked with three different shade styles, it gives you the freedom to manage your workspace environment exactly how you want it.
Download WindowShade X now; for more info, visit Unsanity.com.
[Editor's note: I wasn't ever a windowshade fan in OS 9, but this little utlity's "transparent" WindowShade feature is quite cool - give it a try!]
