Cool Sheep Hot Wolf, a temperature sensitive mug.
Hearing that 2D designs would be easier to place than 3D ones I set my mind to two dimensional designs.
As a product designer I found two dimensions limiting until I found these heat sensitive mugs which reveal another image when a hot drink is added. This allowed me to tell a simple story and have some fun.
I have designed a range of five mugs and made prototypes for two of them.
When Cool Sheep Hot Wolf mug is cool, only the Cool Sheep is visible. Add a hot drink and the Hot Wolf lurking beneath the temperature sensitive layer is revealed.
