Ever wanted to show two different messages with just one object? This model does exactly that!
Shine a light from the left at about -15° and it displays "HATE". Switch to the right at about +15° and it shows "LOVE". Pretty cool, right?
This design is inspired by digital sundial technology. It uses precisely angled optical channels that only let light through from specific directions. It's like having two messages in the same space, just waiting for the right light to reveal them.
