• Blood is an absolutely useless control panel that puts some drops of blood right on your desktop. The drops will float over all your windows and will behave like actual holes in your screen. You may move the drops by dragging them somewhere else or remove them by holding down the option key when you click inside a drop.
• Blood has a complete online documentation you can access with the “Info” button in the control panel. You may save it as a text file and read or print it with a text editor.
