(The tip of a match - Photo taken with a macro lens made out of a Pringles can, by this guy.)I'm always looking for cool DIY things. Even if I rarely actually do them, just thinking and reading about someone who was able to figure out how to do it yourself is pretty cool. Here's an example: Extreme Macro Photography on a Budget. Will I likely ever try to make a lens out of my Pringles can? Probably not. Just that someone actually can do that messes with my brain in a trippy way, though.
