Better yet, watch Arkani-Hamed explain the amplituhedron: http://susy2013.ictp.it/video/05_Friday/2013_08_30_Arkani-Hamed_4-3.html

Apparently Arkani-Hamed's partner in crime, Jaroslav Trnka, did a talk one week earlier. Here are the slides (which mirror Arkani-Hamed's exposition closely): http://www.staff.science.uu.nl/~tonge105/igst13/Trnka.pdf
