Via Dark Roasted Blend.

Rounded corners are one of the fundamental attributes of the Web 2.0 trend. While we are all waiting till when all the browsers are supporting CSS3 border radius property we have to create them by slicing images, writing CSS, making sure IE isn’t screwing around too much, etc. Automating this process seems like the most reasonable solution at the given moment. Rounded Cornr works good, but four images and several CSS rules for one box may be too cluttering, especially if you need more than one variation in your layout. Finally I found the generator that uses absolute minimum of both HTML and CSS, and requires only one image to function—allcrunchy.com.
