See pictures: Pentacle rotates slowly on the floor. When you hop on (sit), your AV hovers (and rotates) over it and it triggers particle effects and a slight glow (if enabled in your client). About 3.5 meters wide.
This version will let you replace the texture (using the standard Edit/Build tool), drop in a different animation, and set color, hovertext, and texture rotation speed in a notecard. It's also set up for free automatic updates in case there are any future improvements.

NOTES: Not for floors with alpha textures. Most floors are fine though.
[Alpha artifacts are a regular SL "feature" -- for example, many heels look funny on dance floors... so you can test your floor by wearing such heels ].
After rezzing, move this down so the pentacle is at ground level (assuming that's what you want).
This object can appear invisible if you are looking from the bottom side.
For example, if, for some reason, it's not facing up, then you may be looking at the "bottom" side.
In that case, click around or use Vew -> Highlight Transparent to see it.
