How about a very cool interior design that is just borked? VVork did this really great clock, except it's not. It only displays times that the designer thought were appropriate for his masterpiece. Like 22:55 (it mirrors in digital display) or repeating numbers: 7:07; counting up or down; 12:34 or 5:43. Yeah! It's not a clock.
Thank Yasser Ballemans for that.
Implications - Art that has an element of deception is appealing to consumers who enjoy a bit of a surprise. Also, there is a vast amount of value in products that are truly interactive, with deceptive pieces calling consumers to make guesses and look beyond outward appearances.
