G.R. N’Namdi, 526 West 26th Street, (212) 929-6645, through March 26.  Mr. Little infuses 60’s Style geometric abstraction with and expansive, sensuous new life. Using a mix of oil and wax on canvases as wide a s nine feet, he creates hard-edged designs of diagonal and vertical bands and long triangles pointing upa and down.  The finely textured surfaces and pulsating colors effect visual and tactile seduction while the kinetic compositions project restless energies.
