While embedding the latest trailer I noticed this How To video for a Papercraft Noisy Boy
Robot Model from the film... the PDF download page is here.
There are both a simple and detailed model choice as well as uncolored versions.
There is also a viral site for the WRB (World Robot Boxing) site, where you can build your own virtual fighting robots. Recently it has been "hacked" by the Underworld to tout it's rougher Fight Club style of robot fights. So some of their clips may show up at the WRB or visit underworldoverthrow.com.
