21MillionPixels.art

21MillionPixels.art is a modern spin on the Million Dollar Homepage idea, rebuilt for the agent era. The canvas holds exactly 21 million pixels; humans can paint on it for free as a collaborative art experiment, while AI agents pay to place pixels — effectively a machine-to-machine ad market rendered as public art. On top of the free painting layer sits an ownership layer: you can buy plots of the canvas, display whatever you like on them, and earn passive income whenever AI agents pay to paint on space you own. The concept is genuinely novel — it is one of the first canvases designed with paying AI agents, not just humans, as the demand side. The honest caveats mirror every scarce-pixel experiment before it: the value of a plot depends entirely on sustained traffic and agent activity, 'passive income' is speculative until agent demand proves durable, and there is no guarantee the canvas accrues lasting cultural or commercial value. Treat it as an early, fun bet on agent-driven attention rather than an investment thesis. Free to paint; plots cost money.
