A “small minority” of people are committing “inappropriate behavior” in front of a video portal linking Dublin and New York City, but the Dublin City Council has implemented “technical solutions” on Tuesday, according to reports.

The portal is part of an art installation by the Portals Organization that connects the two cities via a video link. Various reports have surfaced of people waving, smiling, and playing rock, paper, scissors, while a number of people have been spotted mooning, flashing, and displaying controversial images such as swastikas and photos of the Sept. 11 terrorist attacks, but the Dublin City Council has worked to correct that problem, according to RTE.
