Though the concept is kinda cool I think after a while I would actually avoid these wall clocks if I had them in my house. My brain is complaining after just looking at the picture a couple of times and the colours don’t help either.smh.
How does it work I hear you asking. Well the spiral face turns slowly over 12 hours consequently moving the ball around the spiral. Between every hour there are 4 marks to represent 15 minute intervals. When the balls reaches the 12th hour it falls through the hole in the middle to the bottom to begin it’s journey again.
They retail for £350 which I think is kinda pricey but anyhoo follow the link for more info: http://www.aspiralclocks.com/
