A burned matchstick head.
You know those beautiful super-macro photos that turn something tiny—like a matchstick head — into a detailed and developed and gorgeous work of art? Yeah, you totally don't need a fancy camera to take shots like that for yourself. All you need is a smartphone (really!) and an old keychain laser pointer.It turns out that the tiny lens that focuses the beam inside a cheap laser pointer can also be used with your smartphone camera, letting you get super close-up shots with surprisingly great focus and detail. Just check out the gallery above.
Imgur user mor0n created a tutorial with detailed directions for getting the lens out of the laser pointer. They used a bobby pin and piece of tape to keep the so-small-you'll-lose-it lens secured over their smartphone camera lens.
You can try this, too, to get some self-shot abstract photography for your walls at home. For the best results, you should confirm that your phone's camera has auto-focus and at least a 3MP resolution. And if you don't have a laser pointer lying around — you know, from back when laser pointers were a thing — you can get a laser pointer for less than $5 on Amazon.
