We always knew interactive 3D holograms would be in the future, and now the future is here. The Tokyo Institute of Technology has developed a cooking simulator for aspiring chefs so they can hone their cooking skills without the use of real food. Virtual ingredients are projected onto a frying pan for chefs to stir, and the virtual food moves and changes color as it would in a real frying pan. The simulator also replicates the weight of the food in the pan, so chefs can have a more life-like experience. Now, if only you could smell your virtual culinary creations.
