There are so many good pics on there, I truly love to see that type of stuff, the blood cells are amazing, they do look like the cinammon hot candies.
And the small intestine picture is kinda yucky, but very interesting, I wish there was more than 15.
I'd like to see what a snot looks like, and a toenail and so many other things. I'd like to see infection of whatever kind magnified. I like to see the smalllest of bugs that are invisible to the eye but can be seen this way, example dust mites, skin that falls off the body and makes dust, etc....
