Help me find the name of this object

[regdent]

I was walking past an office today and i saw this object on a table but i have no clue what its called and want to get one for myself.

It is like a small metal dish with sand and there is a metal object with a point which barely toches the sand the metal thing is hanging from an arm and moves on its own creating patterns in the sand.

I thought it was pretty cool and wanted to find out some more information, anyone know what i am talking about??

Thanks

You can get them at www.ThinkGeek.com last time I checked.

..and if I'm wrong..? Well then you can just go FUng Shui (http://www.urbandictionary.com/define.php?term=feng+shui) yourself.
