Scripted Animated Snake Tongue

This tongue will slither out of your mouth between every 12 and 24 seconds, for a fraction of a second, vigorously wiggling, just like with snakes or other reptiles.

To scale the tongue, press Control-Alt-T to highlight transparency first, so you can select it to open up the Edit window.

The script inside is full-perm for the more adventurous, so they can change the appearance time intervals.
