 **Sign:** place your hands as if you were holding a telescope over one eye and rotate your hands as if to zoom in and out.
 
 ## Background
+**Musical background:**
+Inspired by the song "Ode aux casseur/euses" by "la chorale des Canulars" from Lyon. The ode was made in reaction to the media stigmatizing so-called casseur/euses (translated as vandals, rioters. A word used by media to depoliticize anarchist and radical actions). It's an ode to the political actions of these so-called vandals, reminding us that these "violent" actions made great victories possible.

+**History**
+Antitek was created in a poorly insulated home in Lille during the 2023 French pension reform strikes, which fought against a law project raising the retirement age to 64. As of early 2025, the French state is investing in surveillance assets to break the movement and boost the propaganda for nuclear revival.
