It's not a helmet, but "visor", as it's called in LDD, which is put on helmet.

I think it's all "legal". Photos resized + links to originals onklick. It seems there are some problems with site(I could't update page for a long time after publishing) or with photohosting.
To be correct, it was made useing LDD, LDD-to-PovRay converter and PovRay. More information here: http://www.eurobricks.com/forum/index.php?showtopic=71654
