There are a number of simple games I like to play when waiting for a package to download or compile. Often the available themes don’t really suit me, and in any case I like to make themes or skins when I can. One of the easier packages to create an alternate theme for is KDE Mahjongg (kmahjongg), which I will demonstrate here using Inkscape and Gimp. With the 40th anniversary of the Apollo 11 moon landing coming up, a space exploration theme seems appropriate.
