Question about monitor mounts

While looking for deals for a ASUS VH236H, I noticed that the monitor can be attached to a mount. I was wondering if there is a mount out there that can rotate 90 degrees for shmups and had a base, so it didn’t have to be screwed down to a table or wall.

Edit: Finally found what I was looking for. Anyone else interested in a monitor stand that can rotate, this is one I’m currently looking at.
