The only thing the new Meta Cookie system can't seem to do is make your cookie calorie-free.

So, what it can accomplish? The new technology, just introduced at the virtual-reality conference SIGGRAPH, can make you think a boring old sugar cookie is really chocolate or almond-flavored.

How, you ask? A lab technician overlays an image of a flavored cookie onto a plain one, and tubes pump cookie aroma into your nose, tricking your mouth into tasting whatever you see/smell.

The trick lies in the fact that -- as McDonald's knows well -- we taste with our eyes and our nose before a morsel ever touches our tongue. Now, if Tajuki Narumi of Tokyo University could make it so we just inhale Oreo-flavored air and think we're eating chocolatey goodness, science would be talking. And we know Kate Moss would invest.
