For some reason I like this crazy idea: an automatic swear jar that uses web voice-recognition to identify curses, and uses a BitCoin (ugh) API to pay $0.25 to the BitCoin-accepting (?) charity of your choice.
You have to admit, it’s cute. Disregarding the privacy and currency issues, it’s still different. Is it Gamifying behavior change? …or is it re-imagining an old and popular interaction?
