My favorite news reader Vienna has, like all those apps, the ability to define your own display styles and yesterday i made one myself. It is based a bit on the color you see on my site, which for some reason i find nice and and readable.
Just grab the grass.zip, unpack and double click it on your Mac, and you should be set. It comes with the old "you break it, you own both parts" license and no warranty for whatsoever. However you can do with it what you want. The picture inside is a crop from a photo I short myself, so this should really be license free. And what is these days after you unpack(ha!) it?
Update (2006-09-20): I changed the link style in the article, added a readme. Update (2006-09-25): Changed the link style again, less dominating now, more readable.
