Glass Menagerie II

What: Large Creepy Bug Creature
Beer: Centurion's Ghost Ale
Receptacle: Straight sided pint glass
Situation: Official Beer Reading Meeting in the Pickerel following 10th Annual Finland Curry

I've been unable to make sense of most of the photos I took at this meeting. Rob seems to have captured the images more successfully in his post ("Glass menagerie", below).

However, two important images are missing from his collection. The first, above, appeared in my second pint, and shows a large, many-legged, slimy, creepy, bug-like creature stretching around the entire circumference of the glass. Possibly an alien.

This second image appeared approximately an hour later in my third pint of the same beer. I thought initially it was some kind of small scurrying creature, but Rob thought it actually showed the image of a screaming man, probably - due to the hair standing on end - screaming in utter fear.
