Y&R Puerto Rico have hacked vending machines to deliver samples. It may not be the happiness machine, but it's certainly a good reminder to brush your teeth after eating sugary sweets. With each sweet dispensed from the machine, a sample size tube of Colgate is delivered as well. Free positive reinforcement, which may increase consumption of Colgate. If there was a brush delivered with, one could practice good dental hygiene in the schools, club houses and public places where these vending machines are.
Cute idea guys, and judging by the redhead at the pool table, a fun surprise to some vending customers.
