Flavored Ads and Fictional Inspiration

I am always looking for new sensory engagements with consumers. In the Economist: Trading Licks. Word of a researcher inspired by Willy Wonka's flavored and lickable wallpaper to develop flavored and edible films. Think of this included in ads, packaging, store fixtures, etc. Quite a few problems to be solved, like contamination and cost, but I like literature inspiring technology. Roald Dahl, the creator of the Wonka story would have appreciated it. He was inspired by Cadbury chocolate testing at his boarding school in the UK. Technology inspires fiction inspiring technology. There is a network there.
