In the Quartier des Spectacles in Montreal there is this delightful installation - a series of seesaws. As you balance up and down, the light illuminates on the downward side and a tone is emitted. Tones change depending on the height reached.
Up
and
Down

It was great fun to watch the action of people of all ages.
But that was nothing compared to joy of playing on them. My inner child popped out along with gales of laughter. It was nothing like the dreaded days as a child when someone would inevitably try to make you drop rapidly to the ground resulting in a most uncomfortable landing. On this seesaw I felt like I was floating. The accompanying tones added to the delight. It was easy to forget about the winter cold and play!
