Yukino Ohmura uses thousands of bright dot stickers to create these astounding night cityscapes. It is an illusion that disappears when you walk up to the panels.
Yukino says:
Illusion turns out to be truth by keeping a distance from it, and truth may turn out to be illusion too. We are trying to struggle in this world which is filled with uncertain and unstable truths. My artworks are part of the truths cut out from this chaotic world.
