When you place a furnace, smoker, blast furnace, brewing stand, jukebox, or beehive, then armor stands will appear showing you what is inside those blocks. If you set down a campfire, then you can see how long until your food is cooked.
The block with the GUI you want to peep into must have air or water above it.
Brewing stand particles! Since many potions look alike, I made them display particles to distinguish them:
* All potions produce the effect particles of their own color.
* Extended potions produce redstone dust particles.
* Potions strengthened with glowstone dust produce yellow dust particles.
* Awkward potions produce nether wart block particles.
* Thick potions produce glowstone block particles.
* Mundane potions produce cyan terracotta particles.
* Brewing stands currently brewing produce lava particles.
Happy peeping!
