Operating under the premise that, “Art makes a positive difference at all times and in all circumstances” Hauser & Wirth Gallery has reverted to on-line exhibitions and other Internet-accessible strategies to make art available. The gallery’s recently released exhibition walk-through with Light and Space artist Larry Bell wonderfully conveys Bell’s exploration of how glass ‘reflects, absorbs and transmits light.’ We can’t visit the artist’s reflective glass panels right now (seen here in a smaller sculpture), but the next best thing is watching him activate his ‘Standing Wall’ installations to shift the space around him.
