What is i3Void?
i3Void is a blank window that can be used to unobtrusively pad a tiled i3 screen. i3 is a fantastic window manager, but tiling a bunch of windows can be distracting. We are evolutionarily predisposed to notice shiny, colorful, novel things. In scientific terms, a Princeton study found that:
Multiple stimuli present in the visual field at the same time compete for neural representation by mutually suppressing their evoked activity throughout visual cortex, providing a neural correlate for the limited processing capacity of the visual system.
Why not just use a terminal for padding?
My terminal prompt is distracting. It is colorful and full of weird symbols. My prompt tells me all sorts of useful things when I am using the cli, otherwise it is just a colorful mess that clutters my peripheral vision. I relegate my Konsole terminals to one i3 screen with two or three Konsole windows open. I don't need a console on every screen.
Technical Details
i3Void was written using Python and the PyQt4 library. As such, it could easily be used in other tiling window managers.
