To be honest, I no longer use Facebook enough to see any bugs. I basically check in and check out, within 10 or 15 minutes or so each time and never leave an open tab. That being said, just like any website, Facebook has got some bugs. Glitchr is a project that turns common websites into digital art, filled with textual artifacts.
You’ve probably done something like this, whenever Windows used to freeze up, you could drag a window around and create these sort of patterns on your screen. Well, Lithuanian artist Laimonas Zakas‘ Glitchr uses unicode characters to exploit certain programming bugs in popular sites such as Facebook.
While these glitches might seem harmless, some companies have already taken measures to ensure that their sites won’t be “glitchred”. For the time being, you can check out Glitchr on its Facebook page or its Tumblr site. No guarantee that the bugs won’t be fixed by the time you visit, though.
