I often take pictures of objects for this blog when I'm making stuff (such as the Cansole or Home-made 7x7 display) and one constant problem is scale.

There's an inches scale on the left, a centimeters scale on the top and three correctly scaled coins: a one Euro, a US quarter and a British Pound.
I made the image in OmniGraffle and printed it out and then stuck it to the back of an old credit card (actually an old airline mileage card since it wasn't embossed) that I'd sanded down.
