You can click on each one, and it will give an explanation. Some lead to a series of pictures. This one is the one that led me to the site. It reminds me of the cell cake that I made for a final project for my biology class as a freshman in high school.
I wish I had a picture of it. I'm sure there are pictures of it somewhere (unless they washed away when Mom and Dad got flooded during their remodeling), or they're somewhere in my big bog o' pictures that I want to scan.
The only downside to the cake was that the top layer fractured into three pieces on the way to school. It survived and was wonderful, but didn't stay as pretty as I would have liked.
I remember using M&Ms and icing for the nuclear bodies.
