Just a humongous clock for the terminal Type mongoclock in the terminal and it will either, depending on the terminal size, show the time HH:MM or HH:MM:SS with humongous digits. If the terminal is too small, it will not run. mongoclock is designed to be fit on most screens and be readable from all practical distances, so that it can be used in place of a standard wall- or alarm-clock. If the font is not big enough for your (or if it is too large,) just change the font size on your terminal. If it is not the right colour for you, simply change the font colour on your terminal. ☺
