FlySketch is one of the most imaginative Mac applications I’ve found recently. This bite size program lets you scribble and draw over any page on your desktop and keep a snapshot of it. FlySketch lets you set the color, stroke and position and you can draw a number of shapes. I’ve already used it to scribble and write down notes on a few web page designs I like but I believe it can also be used on photos or when creating your own application.
