An anonymous reader writes "Over at the Google Mac Blog, Amit Singh has released GrabFS, which is a MacFUSE filesystem which "shows you a live view of the window contents of currently running applications. In a GrabFS volume, folders represent running applications and image files represent instant screenshots ("grabs") of the applications' windows. You simply copy a file or just open it in place, and you have a screenshot. Open it again, and you have a new screenshot! It's pretty cool actually and looks nice with CoverFlow. For instance I realized that all those Desktop icons are actually individual windows inside Finder.app... and the shadow behind the main menu-bar is a window in itself!"
