At the NJCC convention in America last weekend, there was a custom sculpting company (called Boss Fight) with a booth, showing off some of their recent projects... including some of FunPub's GIJoe and Transformers exclusive heads.

We get a really good look at four of them (Rampage/Shokaract, Chromedome, Eject/Rewind, Thrustinator), and two others are behind them that are a little blurred (Devcon, Cannonball).

The detail on them is really amazing, and it is a shame that the temporary moulds lose a little of it.

I'm not sure if these are being hand-sculpted, or 3D printed from computer generated designs. (I think these days with affordable 3D printers, it is likely the latter)
