While a small number of visitors are allowed at a time in person, the Falmouth Art Center has found a popular way to gather a larger group of people together around its exhibits. At 4 p.m. Monday, center officials will hold another online Zoom teleconference event that introduces new shows in its three galleries. The virtual “receptions” began last September after in-person art receptions were put on hold due to the pandemic. The virtual tours have taken on a life of their own, says executive director Laura Reckford, enlarging on past in-person receptions with what she calls a little more “programming.” Artists now have a chance to talk about their working style and share images or videos of their work. More than 30 viewers have joined in for past online events.
