The creator of this architectural installation, placed in a deserted alley in the city of Quebec, probably got his inspiration after looking at French fries while being on acid. This might be the reason why Les Astronautes called his creation Delirious Frites (frites is another name for French fries). This colorful installation attracts passersby like a magnet, making everyone want to enter the narrow passage between hundreds of foam noodles. Though it may look peculiar during the day, this installation looks even better during the night. The light, shining from above, creates a lot of shadows as it encounters all the “tendrils” that seemingly grow from the very walls of the buildings. This will leave even the sanest person wondering if he isn’t having a delusion.
