Perception Semispheres Set of 8

Eight clear coloured semispheres, smooth to hold, that magnify whatever they sit on by four or five times — and tint it a new colour at the same time.

Place one over a leaf and it leaps closer and turns amber; stack two or three and the colours and magnification combine into something new. It's part magnifier, part colour filter, part beautiful object to hold up to the light. A genuinely open-ended way to explore how looking closer, and looking through colour, changes what you see.
