Germans apparently got a visual reminder of American espionage on Friday night.

In a video posted to YouTube, a German artist can be seen projecting a distinctive image onto the side of the U.S. Embassy in Berlin: President Barack Obama wearing a ball cap backwards, accompanied by the words, “NSA in da House.”

The effect looked something like a cross between hip-hop culture and the Big Brother of George Orwell’s “1984.”

“Germany has called on Washington to end its spying on Europe’s biggest economy after relations between the two nations plunged to a new low in the wake of allegations of US espionage in the nation,” the video description notes. “Berlin expelled the US top intelligence officer in Germany amid claims that two German officials — one working for the domestic secret service (BND) and the other for the Defence Ministry — had handed over sensitive material to Washington.”

In the video, the projection only remains on the side of the building for a few moments before police show up and end the light show.

It’s unclear whether the event took place Friday evening, as some outlets are reporting, or on a different date.

The extent of NSA spying on Germany, a U.S. ally, has sparked concern and outrage in the country, with Chancellor Angela Merkel once comparing NSA surveillance tactics to the Stasi, the communist East German secret police.
