Fête des Lumières

The Lights Festival takes place in Lyon every year around December 8th, during four days of illuminations attractions all over town.
Millions of people (literally!) come to Lyon during this festival, the streets are unbearably crowded. I usually join in the fun with a lot of patience, but not this year, I was too exhausted for that!
So I just went to places I could see without being stepped on and pushed around.
The few places I saw were great though, like these balloons representing algae, floating between the river and its bank...
