Apologies that this isn't completely photography themed. But I thought it's really interesting and, if you weren't sure, explains how lenses / apertures work.

Thanks for posting this Nigel. I have finally gotten into pinhole (after lurking for years). Whenever I get into something, I get excited about it and whenever that happens I bore everyone I know to tears about the subject, haha.

This way I can just send them this link instead of forcing them to watch me draw stuff on a chalkboard (which literally happened last Friday)
