No its not! but it looks like, :-)
I was just playing with some stuff I have and almost by accident it look like a Stabilizer and there you have it, If you want to get an arm injury I can tell you the secret cause this is in no way a stabilizer, LOL.
Well there is only one thing that this setup may work good and is for low angle shots (by turning the whole thing it upside down and the monitor up) I haven't test it yet but as I said, it looks like. I did this just for fun not that I was planning in any way to get a stabilizer.

For those mind genious it may give you more ideas tho...
