I discovered this pretty neat blog via boingboing today (at least that's where I think I found it). This illustration seems to show something that is strangely like an fMRI machine... well with fire instead of magnets, bricks instead of plastic, and smoke instead of a computer analyzing brain images...ohh and instead of the brain images it gives direct insight into the semantic content of the brain.

Check out the BibliOdyssey blog for many many more great illustrations.
