Heat-Sensitive Business Cards Look Like Developing Polaroids [Pics]
The cards, designed by Bureau Rabensteiner, change from black to white when touched.
Austrian graphic design studio Bureau Rabensteiner created a set of thermo-sensitive business cards for Natalie Daniels, a photo producer from Vienna. The black color of the varnish fades at body temperature, so when you hold it in your hands the areas you touch will turn to white.
This allows you to produce different images on the changing surface, like hand prints or lips. The cards' “dynamic and living design” is in a square bordered by a white trim like a classic polaroid.
