Desktop Dolphin Coloring Book is a simple painting application featuring dolphins. The program is very easy to use and intuitive but the interface is not very attractive. However, I really like the marine sounds when pressing buttons. The trial version only includes one image to paint, which is not very attractive, but the full version is supposed to include about 30 images featuring dolphins in different scenes. A great thing is that it supports multiple users and that you can also use the program as a Guest. You can select a different avatar, name and level for every user, as well as customize the icons you wish to show to a certain user. It includes three different age levels, which only vary in the number of colors and available drawing tools. The highest of the three includes an extensive pallet, dropper, and a few simple drawing tools like a straight line, rectangle, circle, color filler, crayon and an eraser. What is more, all the coloring pages can be printed, saved or set as wallpaper. However, the program also has its own disadvantages; it has only one-level undo and the drawings cannot be saved to a bitmap file to edit them in another program. It would be great if the trial version included more than one picture because if judging from the one it includes, I definitely wouldn't buy it. All in all, Desktop Dolphin Coloring Book is a cheap option for a coloring book, but there are much better programs of the kind, for the same money or even less.
