In 2014, a Ukranian blinds company called HoleRoll created this cool idea to transform your windows into nighttime cityscapes cut into blackout curtains. These concept blinds featured silhouettes of iconic skyscrapers which become apparent when the sunlight hits the windows.
“Once you roll it out and the room becomes involved into pleasant half-light, and outside the window appears a beautiful view of the night city or the night sky. The illusion is created by holes in the fabric. Besides the views of the city, roller blinds cast beautiful shadow upon the room and the objects in it. At night “HoleRoll” blinds have the opposite effect, you can see from the outside the shining city skyline or the starry sky,” their official website reads.
