That's a really cool poster... before I buy one though does anyone know if there's anything similar to this in a web picture for free? (smaller is good too).

 

thanks..

That's the best EM chart I've ever seen.

 

I'd like to point out to our members that it can be downloaded for free from the same site, so it's not exclusively an ad and therefore permissible : http://unihedron.com/projects/spectrum/spectrum.pdf
