It's called Billion Dollar Canvas

The idea is to create a massive online canvas where individuals, artists, and businesses can purchase permanent pixel space to display their artwork and link to their projects.
I thought Pixelorama could be a particularly interesting fit since it's an editor specifically made for pixel art. You could showcase artwork created with Pixelorama while linking visitors directly to your project.
I'm currently looking for the first participants, and I'd be interested in hearing what you think of the concept!
