Who knew that Facebook had a secret artistic side? Mathias Bynens did, at least. He recently noticed that Facebook and Instagram automatically turn many public photos into ASCII art just by adding a file extension to the end of the web link -- ".html" if you want a color image, or ".txt" if you'd prefer it in black and white. I've tried the trick with a few of my photos (see above and below for examples), and it definitely works -- the results have a great lo-fi vibe that could work well for a Facebook background image or even a poster.
