Lizard

A lizard that will switch back and forth between resting for up to 2 minutes
and walking to a random spot on an invisible rectangle
at a random speed and with 2 frames of animation.

The script allows you to scale and rotate the "Lizard Walking Area" prim
to define where the lizard can walk. Simply use SL's editing tools.

You can also edit size and material of the lizard without interfering with the script.
Even linking this object to other objects or wearing it is possible.
The script is optimized to cause minimal lag.
