While I was waiting for the traffic light on Sunset to change, I was sipping the coffee I had just bought. Colin Chapman from Lotus, the famous Formula One race team from the Sixties once said: a Grand Prix car should be built to last only to the checkered flag and could fall apart right after.

Well, take-out coffee cups should only last about ten-twenty minutes and disintigrate after that. Falling apart literally because of exposure to air or light. That would be a killer app.
