Why take pictures?

I wish I could say something highly creative or artistic, like: to capture the essence of something, or some other grand purpose. It's not as plain as: to help remember what something looked like either. At the moment I'd say: to take a snapshot of something that struck me as ... non ordinary, whether be it by objective standards or simply from the eye of the beholder - for the possibility that you too may see it.

This video I made with pictures just within a minute of walking distance of where I live.
