Speaking of Minecraft...
I'm playing a team-based survival server on 1.12.2
So far my team is at #1 out of around 30 boards. I am helping with construction of the base and farms within it.
Pulling a lever leads to water being released via a redstone mechanism (that a friend helped to build), washing all of the grain into hoppers which lead to a chest at the end.
Additionally, I've also helped to build a passive cactus farm to the right of the screenshot. Automatically, any growth of cacti is "cut" and washes into a stream of water, which, again, drops into a double chest.
