Mixels Clock: The Glow
Lights off. Game on.

By day it’s a clean pixel clock with a black frame and a white face.
At night that white face glows green, like an old arcade screen still running in the dark.
And it needs no power for that: it charges from light during the day and lights up on its own once the room goes dark.

The specs:

• 8.5 × 8.5 cm: small, but nobody walks past it without noticing
• Glow-in-the-dark face that charges from light and glows green at night
• 3D printed from PLA+, a recycled plastic, so the planet scores a point too
• Slide the back with the arrow, put in the battery, set the time. Level complete
• Battery not included. That’s your side quest
