Want something more complicated in your life? The clock face is too easy to read? Well, get yourself the Seeing Double Wall Clock and you’ll really see double. The clock has a typical clock face and two hands to tell time. But that’s where the conventionality ends. The clock works on the basis of an optical illusion, where the red and green transparent film located on the hands will change according to the minute or hour reading of the hands at a particular time. Thus, the same hands may tell the progression of minutes or hours as indicated by the colour. The clock is powered by a single AA battery.
Singaporeans like to make things difficult, so the invention is not a surprise. It shows off one’s brilliance or superior intelligence. It’s also a conversation piece for guests at your house.
