Comment(by walter):

 re user-defined slides, for example, the C slide would be defined simply
 as:

     def offset_function(x):
         return math.log(x, 10)

     def label_function(x):
         return x

 The LL0 slider is similar:

     def offset_function(x):
         return math.log(x, 10)

     def label_function(x):
         return math.exp(x / 1000)

 The trick will be to do the proper scaling along the axis and printing a
 useful precision for the labels.
