Let stress aside, take your spray bottle and paint a graffiti on your desktop as if it were a wall in your city.
If you are bored when working or studying, this will be a great way to relieve stress. It doesn’t include great features or interface, but it offers you the possibility of having fun when working or studying.
Try your abilities with the sprays, and if somebody comes, only press 'Esc' and everything will be like before.
If you are hours and hours working with your computer, you need Desktop Graffitist to relax yourself.
