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.

Not everything is on Github yet, and much of it is messy and with dependencies on my environment (in the process of cleaning that up), but if you click through the "cross-posted to:" link there are a bunch of links to repo's of what I have pushed so far.
