4-Dimensional Food

Gourmet chefs today have already taken food preparation to its highest form, and now enjoy improvising by presenting the food you order as a 3-dimensional art form on the plate. "Cooking vertically", they say.

I think we're on the cusp of truly four-dimensional food; food that moves and changes over time. I'm not talking about live animals. I mean things like the following:

Food which blossoms decoratively on the plate due to internal frozen parts which expand as they thaw (perhaps helped by a pre-heated section of the plate or the table); for example, a garnish which, rather than just sitting there, does something eventually.

Plates containing mini conveyor belts which move the items on your plate around in decorative flower patterns; the colors merge together creating a moire (strobe lighting in the restaurant or built into the place setting could also enhance the effect)

Food which is like a choose-your-own-adventure plate; the attentive waiter replaces each ingredient with a new ingredient as you eat them, leading you down a path of exploration. For example, the plate starts out with just two ingredients A and B, if you eat B then you get C, if you then eat A, you get D. The ingredients are deftly chosen so you never have incompatible ones.

Molten chocolate cakes (a common dessert that's like a cupcake but filled with hot chocolate syrup) - but this one will slowly leak and erupt by itself, like a volcano, instead of you cutting into it, due to clever construction which vents the steam pressure inside;

Best of all, the new genre of food will be sure to spawn some neat new rules of etiquette. For example "Never eat any food which has not yet turned orange or exploded and which is heading from right to left", or always eat one entire ingredient at a time during the choose-your-own-adventure phase.

Thank you.
