Geoff Hargadon created “13 miniature plastic gates spread across his loft, often tracing the path of his cat, Edie” in a spoof of the Christo and Jeanne-Claude’s Central Park “Gates.” Hargadon — “Hargo,” as he’s now known — had to shut down his Web site featuring photos of “The Somerville Gates” after it received 5.5 million hits in one week. He’s been fielding media calls nonstop and has been interviewed by reporters from Germany to Colombia. The art department at Meredith College in Raleigh, N.C., said Friday that it wants one of the Somerville gates for its collection.”
