Programming in VR Desktop: https://github.com/SimulaVR/Simula (see the README for a link to a video of it in action).

This allows you to (i) distribute your work tasks intuitively across space; (ii) completely zap out all distractions within a VR headset; (iii) completely eliminate the mouse and work 100% on a keyboard (VR Desktop allows you to click and browse with eye gaze).

It takes a bit of practice to learn the keyboard shorcuts (spawning terminals, moving windows, etc with keyboard shortcuts), but once you learn it, it can feel very immersive/productive.
