http://www.miniature-earth.com/ via Stephen Downes who got it from presentation zen which leads to this this YouTube link and this inspirational story.
This came out from following some discussion about the K-12 Online Conference by Stephen including Selling an Idea which I found in my feeds here.
So I started with some squabbling and ended with some hugs. I didn’t even know there this note of discord in among edu bloggers.
If you have a moment the http://www.miniature-earth.com/ is well worth a look, old information i know but beautifully presented.
