Some of the things I buy for my kids I actually buy for myself. Yes, I admit it. Lichtscheibe falls into that category. It is a fascinating little illustration of colour theory: rotate the discs in their primary colours (red, blue and yellow) and combine them with each other to create the secondary colours (purple, orange and green). The suction cup allows you to fix the discs to a window and thus catch and play with the light coming from outside.
Lichtscheibe is beautiful and educational. Total winner. And hey, it’s SWISS! #yay
