the tool promises to you let you (or developers) modify any application without actually modifying it. To do that, the software constantly looks for easily identifiable elements of an application (dialog boxes, scroll bars, buttons, etc.) and then “alters their behavior” by effectively taking over your display, leaving the actual program running in the background and displaying the augmented version instead. According to the researchers, the possibilities from there on out are virtually endless, and include things like adding iTunes buttons to your Word toolbar and tweaking Photoshop to display previews for a whole range of effects at once.
