Border greenery

"ENT-e, 2014'' (robotic installation, video and art intervention, by Gabriela Munguia, in the group show "Last Frontier,''  at the Cantor Art Gallery, at the College of the Holy Cross, Worcester, through April 14.

The show presents some work of contemporary Latin American artists from what the gallery calls "a diverse array of perspectives and geographies.'' The idea is to explore the border/frontier as a "dividing line'' between nations and ''the dissolution of borders through globalization, borders as an experience of 'us' vs. 'them' and the blurring lines between virtual and natural spaces.''

New England is lucky that its border with a foreign nation -- stable, prosperous Canada -- is so much less fraught that the United States's border with Mexico.
