I thought the F-35 helmet looked scary. Then I saw this carbon fibre insectoid helmet and I thought about Nazi UFO pilots coming to invade us from the Moon.
Then I discovered it's not real, and I got giddy and wondered at the perfect 3D work.
Even knowing it's 3D, I can believe it's a real thing made by Lockheed Martin. But the helmet was created by artist Vitaly Bulgarov for a Siggraph 2010 demo of the awesome ultra-realistic 3D rendering engine Keyshot. [Thanks Paquito!]
