To the naked eye this video looks like nothing but a TV screen covered in colourful random static. But there's a secret message hidden in there that only your digital camera can reveal.
Specifically, your digital camera with adequate manual controls so you can set your f-stop to 5.6 and your shutter speed to one full second. If you can get your hands on even a basic DSLR or a micro four-thirds camera then we encourage you to snap away and try it for yourself. But if all you've got access to is a basic point and shoot or your smartphone, the video below will spoil the surprise and show you what you're missing. Or not missing, if you're the easily-startled type. [mfive via PetaPixel]
