From Kaleberg Symbionts:
Volvelleteer is software for making volvelles, those disks with tables of data that you can look at through slots. The program lets you build or import a table of data, set up the slots and then print a front disk with the slots and a back disk with the table of data. The data is generally text, but there is a weak facility for including little pictures.
The application is graphical in nature, but it might have educational applications for teachers.
