A video from the Gesù, the mother church of the Jesuits, in Rome.
As the description says: "Every afternoon at 5:30pm, the newly restored 17th Century machinery of the Pozzi altarpiece at the Altar of St Ignatius is activated. The image of St Ignatius receiving a banner from Christ is lowered to reveal a statue of St Ignatius." [Via Fr B. Who is, I think, the recorder of that video.]
