Poor man Schlieren imaging

I recently learned about Schlieren imaging, got excited by this video, and thought I would try a crude version.
Details may follow eventually, but in the meantime, here are two photos of the air above a flame. (Zoom in on the lower one to see it closer).

Of course both of my brothers were already familiar with it (being a physicist and an aerospace engineer).
