I don't like to sound negative but this looks to me the wrong way to do it.
You are redefining here a UX/UI element: The slider. Well, I like breaking the rules and innovation, but you have to care about the end user. I have been working with computers for over 10 years now, and I didn't figure out what these small circles do until I checked the HN comments.
I might be a little sleepy, it's late here; however, I have strong doubts that any Internet/Computer semi-literate will figure out what this do and how to make it works. This is the case where a 3D shadowed boundaries, little bars and gradient colors can make a huge difference and guide the user to use the tool.
