Biology

I'm becoming increasingly interested in biology, the natural science. I've been Wiki-ing taxonomy, the animal kingdom, and getting all the way from elephants and deers down to images of micro-organisms, parasites and bacteria (I find microscopic images of cells quite beautiful). Did you know humans have 100,000,000,000 neurons in the brain, and elephants have twice as many as that! A sea sponge has none.

All this science is very interesting but so overwhelming! I think I've gotten a bit off track, and only a little bit closer to developing a theme for my mandala.
