If you ever saw/did this then you'll know what I mean. Back in the good ol' days in the vault of glass, at the conflux stage, before you jump down you could jump and around the cliffs to a higher point, at this very high point there was a concrete wall that had a small corner joining the natural Rocky part of the cave, when stood in this corner, the ceiling would literally disappear and show the sun from outside the vault shining into the cave and showed it all lit up in sunlight, that was the coolest view I've seen so far in Destiny :)
