With its allusions to prayer wheels and mandalas, Johansson Projects' latest show, Radialvedic, offers up meditations in the round. Although the three artists here work with different materials — paper, glass, and mixed media — they share a fascination with lines that curve, bend, and spiral. Jill Gallenstein's pen-and-ink drawings resemble seedpods bursting; Kristina Lewis turns zippers, straws, and coffee stirrers into molecular creatures and voluptuous fronds; and Japanese-born Kana Tanaka, trained as a glassblower, sculpts pendulous raindrops that reflect orb-like universes. Visitors should leave the gallery with heads spinning from radiant energy, but at peace.
