If you are really into holographs or rainbow chocolate design, the future looks bright for you. A Swiss startup called Morphotonix developed a way to print holographic rainbow patterns on chocolate.
Chocolate is placed into a special metallic mold, where refractive microstructures are printed on the chocolate's surface. This process creates beautiful images, such as rainbows. This method works on both milk and dark chocolate, but not other types at the moment. Morphotonix is currently looking for a German manufacturer to partner with so this rainbow chocolate can be available.
The healthy, innovative and personalized Photonic chocolate is tastable technology and additive free. This colorful printing method also works on plastic and other 3D surfaces or moldable objects. Although, psychedelic rainbow chocolate definitely sounds the coolest.
