Heat sensitive changing media.

Post by Rick Mainwaring » Thu Dec 22, 2011 2:03 pm

Somebody sent me a link to this rather interesting year calendar, you can write on the coloured squares but the black squares when exposed to the heat from your fingers reveal a fact regarding the date, does anybody know what media and process they used to create this?
