NOTE: This thread's suggestion came from another thread, one on griffins. I would like you to check that out first by clicking right here, because if you don't read it, this will probably make no sense to you. Also, I have changed some of the details about the fan since that thread (like it was called the expolesor), so the information containing the duct may be false. With that said, let us move on!
Main Idea For Making This Thread:
I came up with this idea (I'm embarrassed to admit it) on the spot editing my first thread, about griffins. However, the more and more I thought about it, I realized this block could become a fundamental part of Minecraft and that this thing needs to be talked about more.
What's An Fan?
Imagine a dispenser/dropper, and then add the fan, as the three would become a trio of items that dispense things. Dispenser dispense rapidly, droppers dispense not as rapidly and the fan dispenses wind. It would be found in the redstone menu on the creative guide, and would be what I think is a great addition to Minecraft.
The fan would have the same background texture and color and size as the dispenser, and would have a hole, much like if you place a dispenser face up, however this hole would be visible whatever way you place an duct. (it cannot be placed up and down, unlike a dispenser) Also, eyes are not visible, it is just the hole. The hole also has a light blue ring surrounding it.
The wind that would be "fanned" from the fan would look like white waves, however they are contained within a three wide, one tall and seven long block radius.They would push out until the end of the radius, when they fade away softly.
The fab dispenses wind out of its hole with the range mentioned above underlined. With the three wide part, I devised a chart to show you how it would work:
