Sliders for control pages

Has anybody developed a slider for the control pages? I saw a question asked back in 2010.
I wanted to use them for Volume, Lights and HVAC

Not a slider per se, but I made these graphics that get most of the way there. What I do is place 10 transparent buttons across the range of values representing 10, 20, 30... percent on top of the image file.

The files are here: https://github.com/DaveL17/Graphics/tree/master/theme-purple/slider-310

There are other sliders in different theme folders, too. The violet one is my personal favorite. All of the images in that repo are free to use.

Dave, I had done the same with the one below but was hoping to find something that moved in better/smaller increments.
I suppose I could make each oval a different temp.

It would take some work getting it linked to Indigo, but there are tons of javascript sliders out there.
