How to get this Widget? Help please!

Hi everyone! 

I have a Motorola Xoom (and i love it.), runing Android 3.1, and i always wanted to have the widget in the image below.

I think it should be really easy to get it, but i really have no idea of where to get it.

If some of you can help me, i thank you VEEERY much!
