According to tech blog Gizmodo, Disney has been awarded a patent for so-called "interactive cakes," cakes equipped with miniature projectors that can produce simulations of landscapes and, naturally, Disney characters.
Okay. That's weird enough. But, how would the cakes be interactive? When cutting a slice or using specially coded utensils, the projectors might instantly create a special effect. For example, Captain Hook might instantly appear and draw his sword as one approaches the cake with a knife.
The website StitchKingdom has more details on the technological possibilities of interactive cakes:
The system would be capable of detecting the topography of a cake which essentially means that if a slice were to be cut out, it could detect the missing piece and respond appropriately. For example, cut out a slice where there’s a simulated lake and you may instantly create a waterfall in which water is now represented as flowing down the sides of the new missing cake portion. Additionally, props and specially coded utensils could trigger events such as Tinker Bell flying around the cake and leaving a trail of pixie dust when someone waves a wand in front of the cake. Perhaps Captain Hook would instantly appear and draw his sword, preparing for battle, as someone approaches the cake with a knife.
