Pairs is a kde educational game meant for children . https://userbase.kde.org/Pairs 

• You will need to design SVG images using inkscape for Pairs themes
• Be creative
• Use inkscape, save your images in svg format
• Make sure they are identifiable 
• SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, andcompressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software.
• Images are to be used further through the XML files
• An invisible background in svg images are preferable
• Images should be about different flags across the globe
