I have been in Switzerland for a few weeks and everywhere I look I see polka dots. Let me illustrate with a few examples.A Polka dot park at EPFL in Lausanne
Polka dot fountain spotted at Pierre Gianadda Foundation in Martigny. This one moved in circular motion while squirting water.
Whatever the reason is, I am simply in love with this country. My obsession with polka dots is documented here.
