I found this interesting Clock at Technabob. It’s Karlsson Station Numbers Hologram Clock with 2 faces in different point of view.
It’s something important to have unique stuff hanging around our home walls as it will gives a different taste of life. I’m not sure what kind of technology this clock has. But thanks to technabob, I’ve learn about Lenticular printing illusion today.
According to technabob, Karlsson Station Numbers Hologram Clock has this illusion stuff which trick our dumb eyes into seeing a double face of the clock.
