Just a quick one but the Swiss National Park is currently running a mini exposition at the Maladière Centre this week. It ends tomorrow but I would recommend doing your weekend shop there with the kids as they have some pretty cool mechanical origami structures of different animals which my 2 adored.
Most of the structures are Swiss animals:
But others are less so:
They also have some Zeotropes which you will remember from your childhood as the spinning cylinder with slits in the side that produces a moving image. I was so thrilled that E got to see one of these as I remember them from my childhood and haven’t seen one since. Who knows we may try creating our own next!
