Amazing molecular-biology video

http://cosmicvariance.com/2006/09/29/the-cell-is-like-tron/

It's a video of the major processses happening inside a cell: building and unbuilding of the microtubules and actin fibres that are the cell's skeleton and reinforcing rods, transcribing enzymes whizzing down a stream of DNA and writing RNA, the ribosomes of the translation machinery zipping down an RNA molecule and extruding a protein, kinesin walking down a tubule carrying a vesicle. It's pretty accurate - the proteins have the shapes which crystallographers worked out for them.

Some of you have already seen it, but while talking to aldabra after tidying up her garden this afternoon I discovered that she hadn't.
