A single large eye made the Alien into a `cyclop`.
Veins for pumping blood were made for plasticized PVC tube and an internal peristaltic pump was used to make the blood flow.
As the latex skin was semi translucent a light strobing system inside the Alien proved to be quite effective.
The final disgusting slimy skin was made by randomly throwing expanding Polyurethane over the latex skin. A dribble of oil & `Slime` completed the effect….
A bit smelly, but a good effort to represent Keith Wilson`s sketch.
