This theme is sort of a mix of influences, but I was inspired by the "Dimples" Mac OS9 theme. I also wouldn't be terribly surprised if something similar to this had been made at some point in the X11 past.

The theme is based on a titlebar with a sort of dot texture. For an embossed texture, download "Boss," for a impressed texture, download "Punktate." So far I have only made versions for the Platinum color-scheme, and my New Earthtones color-scheme, but if you want another color-scheme, you can download the Krita docs from my git and customize as much as you would like.

I also thought that this theme could work okay using the Smaragd plugin for KWin, with a few sacrifices, so I have made versions of Punktate, specifically, adjusted to better work around the limitations of Smaragd.
