If you have to either give your personal details or $5 to use the program, it is not a freeware. This is an abuse of the word.
Also, that thing replaced my background picture without asking me anything, and it replaced it with a highly pixelated thing with enormous black bands at the top and bottom. Maybe SubRosaThing ought to give larger screens to their programmers. a 640x480 picture to a 1920x1200 desktop doesn't cut it.
Furthermore the program didn't restore the original picture when quitting. Doh.
