[vrfileman] / NOTES

- cyberpunk aesthetic: don't forget the mandatory grids and purple-ish horizon
  gradients.
- point of view inside a directory node
- files in this directory are geometric shapes around the user
- some gesture for scrolling through them like in a tunnel if they are more than
  fit in the screen
- point with laser sight to files, and grab them, at which point show a minature
  of each file next to the manipulator
- subdirectories as links going off to the bottom somehow, select them to
  traverse the tree
- parent directory link going off above...
- when sorting files, do transition and move them around.
