I'm glad I found this again after losing all my bookmarks when the computer died. I'm a GM of the rpg Dragon Storm, and have used this to create monsters. I'd like to share the link with my gaming community, if that's all right.
My most successful creature from here had this description:
You are spelunking and you blink to find yourself thinking about something strange.
This monster has 8 arms, 3 torsos, 3 wings, 4 tails.
This monster invades your thoughts like Hell.
It wants a lock of your hair.
I had it brachiating through the trees with its tails instead of a cave encounter, but even before the players could see it, they were getting segments of songs from the musical Hair sung directly into their minds. Its arms ended in scissor-like claws so it could shear people.
