The graphics in Tux Math and Tux Typing are of varying quality. Decide which images look too amateurish to you, and create more professional-looking replacements. Ideally, the images should be in Scalable Vector Graphics (SVG) format. These images can be created with the proprietary Adobe Illustrator program, or the Free/Open Source program "Inkscape" (http://inkscape.org). This task may be done more than once. (aviraldg: Before the program actually starts, I think we should actually clarify about exactly which graphics need to be redone.)
