I doubt it, it's related to the Grasmannian stuff that Arkani-Hamed has been evangelising for some time, and which grew out of the twistor-string models.

Would like to listen to the lecture that CdP linked but at work. Damn!

Oh here are the slides. OK, just worked out for N=4 Supersymmetric Yang Mills theory so far (N is the number of supercharges - see the twistor string thread. When I look at that thread, I can't see any of the fucking diagrams any more. It's been fucked since the server move :( )

Anyway, I'm not burning my QFT books just yet

It reads like "Feynman Gets A severe Grass/Haircut-mann" , so far... :thumbup:
By 'it', of corse, i mean : this
