Leading off last week’s Streets: World Roundup is this amazing mural (seen above) painted over the course of a year by Josef Kristofoletti. The project was commissioned by the ATLAS Experiment at CERN, the European Organization for Nuclear Research and was painted on the side of the ATLAS control room directly above the detector, near the Swiss-French border outside of Geneva by the Texas-based artist. It depicts the artist’s interpretation of what the Higgs boson might look like. For those interested, Kristofoletti also sent us a link for a time-lapse of the project here.

Other street activity worth noting include walls from Sten & Lex – Italy, Dal East – South Africa, Shok-1 – London, Mesa – Spain, Escif – Spain, Titifreak – Netherlands, Ericailcane – Spain (source), Pixel Pancho – Russia (source), Augustine Kofie & ZEDZ – Netherlands, Daim – Italy (source), M-City – Poland, Faith47 – South Africa (source), and Philippe Hérard – Paris (source).
