Unicorn
Feeling down? Need a pick me up? Well, boy howdy, do I have the solution for you. That's right, with one, magical click of the mouse (or trackpad, or what-have-you), you can have your very own cure for the doldrums. It's time to turn that frown upside-down. Stop being a negative-Nancy. No need to be a sourpuss-Stu.
May I present you with the wonderful cure-all? It's a free unicorn illustration, complete with rainbow horn, magical stars, and a very uplifting "Yay!".
It's available as an Adobe Illustrator file.
