This has been a banner month for the future of protests. First, a Snowden statue was replaced with a hologram after being torn down in a Brooklyn park, and on Sunday, a group of hologram protesters marched in front of the Spanish building where the country's Congress of Deputies meets.

As Fusion reports, the march, aside from being an impressive technical feat, was deeply ironic. The group behind the protest, No Somos Delito, was acting against the extremely controversial new "citizen security" law in the country, which places limits on freedom of expression, and specifically freedom of protest. Spaniards in violation of the law, which comes into effect this July unless beaten by a legal challenge, will face fines of several thousand euros for unauthorized protests.

Organizers have set up an appropriately futuristic website for the project, called Holograms por la Libertad, or Holograms for Freedom. "With the passing of the 'gag' law, you won't be allowed to demonstrate in front of Congress," a woman tells the viewer before becoming a hologram.
