Billy Wilburn and Corey Shelsta
South Dakota State University Theatre
These two wrote out in detail how they made these fans so if you are interested in such a project you can take a look at their link below.

What they say in the beginning is very true, these fans are a bit expensive, but if you are not into the project you can buy the fan HERE.
But if you are going to go for it with this kind of project then we have just the feathers that you are going to be needing.
If you try this out, take some pictures and share them with us.
