I would like a Wind Physics engine as well as a fan block to go with it for adventure maps (Redstone only), as well as animations for the fan when on/off (and tiny grass / stone particles flying across the path depending on what blocks are below the wind from the fan. Fans are set to be at one speed, forceful enough to push a player up / away from the fan.
The wind engine would be able to blow leaves away if fast enough (can make them entities and throw them to the ground or against walls, etc). Also include a place-able blocky wind sock that can have different colors based on what wool blocks you use to make it. (Bow recipe, but with wool blocks.) It can only be placed on fences and cobblestone wall corners/posts. This can show the speed of the wind currently. It will have an entity animation as well, swaying slowly for slow speeds (idle downward if no speed or swaying slightly when down with very little speed) and barely-seeable swaying almost pure outright at very fast speeds.
