Facebook rears its agreeable thumb on countless websites, so perhaps the Like Button Tip Box is a way to bring value rating back to an action that simply asks for a positive or negative opinion.
Designed by Burak Kaynak, this clever social networking-inspired strongbox is strapped with an icon that frequent Internet users know all too well--the blue and white thumbs-up symbol. The safe itself comes in the shape of the on-screen button. The concept is simple, yet more complex than the "to click, or not to click" situation, kindly asking to be filled with a monetary contribution equivalent to one's agreement with the affirmative statement.
I'd imagine that the Like Button Tip Box would be quite a novelty and consequent success on coffee shop counters, restaurant cashiers and placed tactfully beside street buskers. Even if the service wouldn't warrant a full Facebook like, perhaps a five-cent donation would still be appropriate?
