After viewing some recent rather interest experiments in CSS3, I decided to do some experimenting of my own. CSS3 brings a lot more variety to the table regarding what you can do with it when compared to CSS2.1. Rounded corners, scaling and rotations are all possible with just a basic knowledge of mathematics! It got me thinking, what could I create, using only CSS, that would normally require images? So, I decided to try and create some of the flags of the world.

Nice example on how-to use CSS to create stunning images

During the past couple months, the Knol team has been steadily adding improved tools to help you create better knols. Most notably, we've greatly expanded the number of embeddable objects to help you make your knols more graphical and interactive. We've been excited by the many uses we're seeing, and today we have one more to add to the list: PicApp.

Nice feature, looks like the knol site becomes more and more a community site like "hub pages".
I'm wondering if you write a copy for Knol, using their images, if republishing an article including images is legal.

At the end knol needs some more visitors, for sure...
