LIVE PREVIEW: http://www.secondwindprojects.com/soothe/
This is a theme I had developed for 2.0.18 and eventually intended to release as a premium theme. But with 2.1 around the corner, not enough time to finish this theme properly, and not enough time to convert it to 2.1, I've decided to just go ahead and release it as a free theme on vanillaforums.org!
Note that I will also, not surprisingly, not have much time to devote to supporting this theme either, so use at your own risk.
Oh, btw, this theme uses LESS CSS, so you can customize the color scheme in some nifty ways. Just open up the custom.less file and find the section marked "COLOR SCHEME MODIFICATIONS," then go to town. There are some basic instructions included in the file. You can change the hue, lightness, and saturation of all the default colors to create a new-ish theme (or set all your own values).
