About this project
What does AC Unit add?
This mod adds 4 animated decoration blocks: AC Unit (indoor) AC Unit (outdoor) Fan Ceiling Fan
Each one of them have sound effects when they work (right click or redstone activation). Animations with the exception for outdoor unit but it has particles (dripping water) instead.
I forgot to show a ceiling a fan in the video so just imagine it. You put it on a ceiling and it spins.
