A cardboard slide rule

I hope to improve this, but for now I have an image of a pair of log scales that you can print out, stick onto a piece of card, and cut along the centre line to make a simple two-scale slide rule (C and D scales).

Log scale image.

(This image is just black and white. Sometimes, on 256-colour displays, this seems to display as white on white, due to some palette cock-up. If this happens, just save the image file from the browser, and open it in some decent image handling application, such as Paint Shop Pro, and print it from there. It'll look better that way anyway.)
