:w saves - Black Text for Vi/Vim Users T-Shirt

Many programmers and system administrators use Vi/Vim to edit text and know all the important commands by heart. New users, especially those accustomed to GUIs, are often baffled by the text-only user interface. This design simply consists of the text ":w saves" in a bold black font. It helps you remember one of the most essential commands, i. e. how to save (write) a file. Obviously you should also know how to quit, unless you want to generate a random string. The design is available in black on grey and several other shirt colours.
