The human ability to see faces in everyday objects is well documented. Admittedly this is a little Domokunesque, but face-like none the less. I wonder to what extent this was the result of deliberate design choices? The red of the key makes it a target for grabbing, but could be interpreted as a tongue. Can the design of the keys be stretched into themed tongues?
Most of the hotel room keys in Finland I’ve come across have been VingCards – plastic, durable, boring. After 3 weeks on the road its pleasant to carry something more natural in my back pocket, even if it is only veneer.
