These icons can be those of older versions (CS3), or more up-to-date versions (CS5). In addition, you can also create star-shaped insignias, using whatever text you want to fill them in and changing them to whatever color you like.
Using the application is very easy, since you only need to choose the background color and the font, and choose the words you want to appear. Of course, if you check out the advanced options, you can also add shadows and even adjust contrast.
Icon Generator Pro is a neat tool that might be especially appreciated by Window's users, since your desktop will look great with the new icons.
