Yummy Virtual Cookies
A device that lets you virtually change the flavor and appearance a cookie while eating it. With “Metacookie +” the user (eater?) is hooked up to goggles so they can see the design of the cookie that they are eating. The taste is simulated by synthesized scents delivered by seven tubes.
I’ve been racking my brain to think of how this could be used commercially. Probably in future when all plant and animal life is wiped out. And all we have to eat is a gruel of synthesized carbohydrates and amino acids we can pretend it’s a Big Mac.
