The Book You Have to Bake Before You Can Read

From Dezeen.com:

Croatian creative agency Bruketa & Zinić have designed an annual report for food company Podravka that has to be baked in an oven before it can be read.

Called Well Done, the report features blank pages printed with thermo-reactive ink that, after being wrapped in foil and cooked for 25 minutes, reveal text and images.
