Imagine pointing to a landscape painting and knowing that you own the sky or the stars. Meanwhile, an anonymous collector in Tokyo owns the lone figure in the background and an AI in London controls the snaking river running through the piece. All three of you alter the painting at any time within parameters designed by the artist. You might, depending on your artistic whim, change the sky from day to night while the Tokyo collector may lie dormant for years... throughout the entire time, the AI adjusts the saturation of the river’s water based on daily stock market volatility. 

Welcome to 21st century art.
