Oh me, oh my. (serious nerdcore bio-geek moment)

Whilst looking for an illustration of a particular concept in biology (specifically, the density of molecules in the cytoplasm of a cell) to use in my lecture tomorrow morning, I came across David Goodsell's The Machinery of Life. Just click through to the reduced illustrations in there (especially this, this, and this). There are also some lovely illustrations of the structure of various macromolecules (DNA, RNA, proteins) as well as some of the processes of life. Dig through there, it's just amazing.
