Unix Days autonomously paints the color of each day. It runs on the Ethereum blockchain, without dependencies or human intervention. Each color is calculated by hashing the number of days since the Unix epoch (midnight on January 1st, 1970) and interpreting the first 6 bytes as a hex color. This means the color is materially connected to the day itself—it is the color of that day, in some sense.
The rhythm might intuitively recall the experience of passing days: infinite gradation, monotonous repetition. Beauty and boredom. Finding meaning even with little room for choice.
The fantasy of technological permanence often obscures the fragility of human attention spans and lifespans. Maybe we can appropriate decentralized technologies to subvert that effect. You can mint a color as a memento (free, unlimited) and check back from time to time to see what color today is.
