I am trying to create a slider that grows like this:

At first I started making a logarithmic slider, but actually did not match the required shortcuts. I canβt figure out how to achieve this. Any ideas?
The difficulty lies in the fact that as you move the slider, the increment changes: 5 β 10, 10 β 100, 500 β 1000, etc.
Here is the slider daemon you can play with: http://jsfiddle.net/jdefcswv/2/
Thanks!
(for some reason SO wants me to put the code here)
