I just discovered a nice gallery of pgf examples. This is a figure from Rumelhart and McClelland 1986 showing the structure of their model of parallel distributed processing. I am posting this example there, and here as well. First of all the picture:
And next the latex code: (notice the foreach loops – very cool!!!)

The picture looks cool, but how much coding has gone into it. is it worth doing all the hard coding.

Hi informative site. I thought go karting london might be useful as it discusses some similar subjects. Anyway keep up the fantastic work, this is now one of my top 10 sites!
