I uploaded the schlieren images/video I took this weekend. I improved the illumination and focusing, so that a larger volume was imaged, to good effect I think. I am thinking of putting together an instructable, and a thingiverse thing with my 3D printed optical mounts in the near future.

I finally got my Nikon F-mount Pinhole Lens up on Thingiverse. You can see it at: http://www.thingiverse.com/thing:20993. Here is a link to a Flickr set with some photos of the lens and some images I took with it. http://www.flickr.com/photos/k0v0/sets/72157629762934733/
This is the pinhole attachment.
This was my favorite image.
The website looks great Luc!
