We went to a rugby match last night (Racing 92 vs La Rochelle), at the U Arena. It was a great match! On our way home afterwards, we walked underneath the Grande Arche at La Défense. This scene caught my eye as I walked up the steps. There are various glass panels (a mini maze of them) and as I walked towards them, everything immediately behind became distorted. This was better in colour, as the light behind the glass was blue - but I think you can still see the distortion, even in black and white.
