When people squeeze out ideas, it is usually a single bag of
  frosting in a single color and a single flavor.

  But, what if you could frost the entire cake at once, with every
  flavor and every color all at once, even with flavors we cannot
  taste, and colors we cannot see?

  If you can imagine what such a machine would look like and how
  the cake would taste and how it works and smells at the same
  time - let me know!
