The Cthulhoid Test

Have you ever wondered whether the person sitting at the terminal next to you might not actually be a Cthulhoid godling in disguise? Have you ever puzzled about the fact that small children seem to mysteriously vanish when they're in their presence? That occasionally you have the feeling that they're watching you. Hungrily. Or pondered on why they need those extra eyes on stalks, or the tentacles, or the claws, the teeth, and the fiery breath (even when they *haven't* been eating Thai food)? Well, with this simple test you can find out once and for all:
IS YOUR NEIGHBOUR REALLY NYARLATHOTEP IN DISGUISE?
IS THAT CTHULHU SITTING BEHIND YOU OR JUST YOUR CAT?
WHY HAS YOUR DOG SUDDENLY ACQUIRED RED GLOWING EYES AND A TONGUE WHICH WOULD MAKE A KOMODO DRAGON GASP IN DISBELIEF?
WAS THE HIGHWAY UNDERPASS REALLY DUG BY THE LOCAL COUNCIL, OR IS THERE A CHTHONIAN ON THE LOCAL BOARD OF ENGINEERS?

To find out, start here:

Can you see the person at the terminal next to you?

Yes Somtimes No
