I made it at Techshop. http://www.techshop.ws/
With the microphone on the front of my sports video camera; I needed to get something to reduce the wind noise. I looked on-line but did not like what I saw. I did not want to glue something on, just to peel it off. So, I came up with a clip on foam wind noise reducer.
Using foam from head phones and a coated paper clip.
