Hey look, a cell!

This is what they look like. If you happen to look in false color.

For some reason Wired's science blog doesn't have an actual link to wherever this comes from internet-wise. Real world-wise it was created by the European Molecular Biology Laboratory, and is to be published in Nature. In this photo is a skin cell, flash-frozen to preserve its normal appearance and electron microscoped from multiple angles to create a 3D image. The color legend goes:

Cell-cell contact: brown, nucleus: blue, microtubules: green , mitochondria: purple, endoplasmic reiculum: steel blue.

So it seems that they weren't just making it up in high school biology.
