Mystery Object

I remembered to take a photo at school today! This is an item that currently resides in my office and is not used as much as it should be. In fact, I should try to remember that I have it on Wednesday. I took a few photos from different angles, but have decided to go with a view from above.

Have you guessed what it is yet?

I'm uploading some more of today's shots to Flickr - will try and remember to link to them later.
