Video: AfterEffects: Predator Effect

The transparency effect like in the movie Predator.[According to me,that's the scariest Alien i have ever seen till date!].I dont have a green screen setup yet,so i used a Biped rendered out as TGA sequence as the displacement map over the static background.

PS:The biped is actually doing a ballet,but comeon,there are pre-cogs,hunters,breeders and eccentric "ballet dancers" in predator world!

Also FYI,This is how the effect was done in the original 1987 Predator movie:

The invisibility effect was achieved by having someone in a bright red suit (because it was the farthest opposite of the green of the jungle and the blue of the sky) the size of the creature. The take was then repeated without the actors using a 30% wider lens on the camera. When the two takes were combined optically, a vague outline of the alien could be seen with the background scenery bending around its shape.[From Wikipedia]
