Most of my workspaces are tiling (bspwm), but I have one where all windows are floated.

This is showcasing my own (very minimalist; ~300 lines) unreleased desktop manager written in pure Ruby, using a Ruby font renderer and Ruby X11 client library (both on github), and showing a custom menu written in Ruby that auto-populates with actions based on directory contents, and showing my Ruby terminal showcasing double-width and double-height support (xterm has it, but few others), and a window showing me editing my Ruby text editor with itself…

Oh, and Polybar. One of the terminals is st - the Ruby terminal is a bit wobbly in a few respects still, though I use it more and more. So there are a few non-Ruby bits left. So far.
