"kepler" is a hostname for my Fujitsu ArrowsTab/Stylistic Q509/VE device, the name is taken from NASA's discovered exoplanet named "Kepler-22b".
Although, the color scheme and theme in my i3 environment doesn't resemble a "Kepler" exoplanet at all.
Color scheme and theme is inspired by well-known version of Damn Small Linux, with a recreation of its original wallpaper.
