If you have a need for accuracy in return loss to SWR or dB to gain 
conversion, these two links will fill a need and show you how to make a 
cute little circular slide rule tool.

The first link explains how TK5EP made the chart and gives a link to a 
PDF file for printing it.
The second link shows how VE3IVM extended the project by adding a couple 
CDROM blanks to make it a robust tool.

Maybe you can think of something similar to make another version of the 
tool.....
