Belgium, eyewear designer Theo is known for their quirky and fun designs. Their first entry into jewelry is called the Hypnotic Series, making an optical illusion into a piece of wearable art. I can see this as a bow tie or a scarf pin or even on a hat. Theo did a pretty good job here, try staring at these for a few minutes.. you can definitely feel the hypnotic vibe. A little spooky, which makes this an excellent design.
