This is a great example of content that needs to be on the XO.  I found this .svg (scalable vector graphics) file over at wiki commons, which is a great source for educational images.  It’s where I found the images for the Dinosaur eBook actually.

The translation for this image shouldn’t be too hard either.  While IE doesn’t display .svg file in a web page (I had to reformat this to jpg) good browsers do, like firefox and the Browse activity on the XO.  If you don’t have firefox, I highly suggest you download it.  And if you download it from the link to the right > I make a couple bucks.  Firefox is free to you of course, as software should be.
