Today’s invention is a simple add-on to online shopping kart systems, based on the recent finding that we seem to have an irresistible urge to mimic what other people are doing.

Not only does this satisfy some kind of voyeuristic tendency, but shoppers can then simply click on these items to add them to their own kart.
