Moon glass reveals the phases of the moon as you drink

The curved bottom of the cup peeks through your drink as the level drops down, moving the "moon" from full to a fingernail-paring sliver. Of course, it works better if you drink something cloudy and white — it's designed some cloudy Korean rice-wines, but would also work with Pernod and water, I'm thinking.
