The Sevres Vase Clock
"An adjustable hammer gently knocks on any vase you place on the stand on the hour, every hour. Different vases produce different sounds so potentially every home’s clock looks and sounds different just from one device."
"Designer Vadim Kibardin Black & White Clock, four independent 3D OLED digits, each digit with their own power source and control. This clock has a light sensor, it can automatically switch two modes: the figures are white in the dark time of day and black at daytime."
