Frosting Printer: The Lazy Way to an Ugly Birthday Cake

AutoFrost is a cake decorator imagined, designed, and built by students at Franklin W. Olin College of Engineering for the Principles of Engineering class. According to the students' site:
We set out to create a cake-frosting machine which would allow the user to design a cake in a paint-like GUI created in Python, and which, at the press of a button, would draw whatever was on the GUI in frosting (dispensed evenly with a servo).
They used a pretty basic design for video, but it replicated the text almost exactly, which is impressive. It's not the prettiest birthday cake, but it's definitely got the kewlest production!
