This is not an ordinary clock with regular shapes like circle, oval. etc.(although the functions are the same)
What I am going to introduce is Time Cube.
Time Cube had a series of layered triangles which rotate to tell the time. The largest triangle displays hours, while the medium-sized one tells minutes, and the small spinning triangle on top acts as a second hand.
You may think it will be confusing to read (i thought so too) which actually is not. Think about triangles like the hands on a regular clock and it will not be difficult.
I think this is quite cool for a clock to be in this shape but i don't think I will buy because it's too troublesome for me to think about the clock and get used to it.
