Rotating Vesa Plate

[KIIIDDD]

I am looking for a plate that will mount to a 75X75 vesa mount so that the monitor can rotate on the mount. I did a bit of googling and came up with nothing i am probably just calling it something wrong because some one has to make something like that

I'm interested in something like this too, a 100x100 version.
