Glassrain is an installation from 1984, one of the first of Rúrí‘s many works that address the theme of time and menace. Glassrain comprises 500 razor-sharp fragments of glass, each ending in a point; the glass sheets, of variable length, hang in clusters from ceiling to floor. Each piece is suspended on a clear thread, and when a visitor walks past the piece, air currents lead the glass pieces to turn on their threads.
