In Warbreaker we see Lightsong being effected by a particular painting which works together with his dreams and clearly some Spiritual Realm/Fortune shenanigans.
In Oathbringer, Kaladin touches Riino's shiny globe and gets a vision. Later in Celebrant (ch. 102) Kaladin notices a painting where he sees the same image as in his vision.
If a Spinner (chromium Ferring) tapped Fortune while looking at art, would that give them a chance to peak into the Spiritual Realm?
