Unusual default interface alterations

Hm. I can’t figure out how to phrase that better. Anyhow, here’s my question: How many people have altered the default interface to something different? Would anybody be willing to take a screenshot?

This page has a number of different color schemes, but not interface setups.

My usual setup is just the default one, but with the 3D viewport split in two divisions vertically. At the moment my color scheme is dark gray with a few different hues thrown in to add color to the buttons.
