So far I love Lion but what is with iCal's leather titlebar? Seems very out of place next to mail.app and I couldn't find a way to change it to a more minimal scheme. So I replaced the artwork files in iCal with gray / aluminum ones using the same shades as Mail. The only thing I couldn't change was the slightly-off-black color of the text (I assume it's coded someplace), but I still prefer it. I hope its ok to post a link to it here, it doesn't contain any apple software, just my images: - http://macnix.blogspot.com/2011/07/change-mac-os-x-107-lion-ical-skin-to.html Hope others find it useful.
