I bought a box of used Destiny toys from someone, and it came with an icecube tray to make ice shaped like Hive Runes. I don't usually have company over that would appreciate rune-shaped ice in their drink, so I used the tray as a mold to make these funny things out of clay.
No, I haven't tried locking doors with them, yet.
Original design belongs to Bungie. This is my funny fan art.
