Banclock alarm forces you to save
Banclock is a cubic alarm clock from Japan that has no off switch or snooze button. The only way you can turn it off is by feeding it some coins every morning. It was designed to force you to save a little money every day, but it's constant beeping would only remind me of how poor I am. Every morning when I couldn't find any change to give it I'd just lie in bed crying, listening to the beeping of my own failure.
