Well, just customize Readable (http://readable.tastefulwords.com/?setup) to your heart's content. Then, get in touch, and send me the custom options you used.

If the theme is awesome, I'll add it to Readable's selection of themes (http://readable.tastefulwords.com/?setup#explain-style-theme...). Did you try those out, by the way?

If you know CSS, you can also heavily customize Readable via the "More CSS" option.
