Vitrine holds a catalogue of roughly — plates. It shows one at a time, for nine seconds, and keeps nothing. There is no history, no reload of what has gone, no gallery.

You may keep one. The button admits a single specimen into the frame at lower left, permanently, and then closes for good. There is no undo and no second choice.

Everything else that passes through here has been seen by no one else and will not come back.

Tap anywhere to close.
