A long time ago computers didn’t have graphics. All they could do was show green characters on a black screen or black characters on white paper.But programmers were resourceful. They discovered that if you filled the screen with certain characters and squinted you could sort of make out a picture. Thus ASCII art was born.The ASCII cam application lets you view the world as ASCII art using the camera on an Android device. Characters are displayed as green-on-black, white-on-black, or, for that line printer look, as dark-grey-on-white.It’s just the thing for Android owners suffering iPhone envy: a photography application that’s even more retro than Hipstamatic. Short of simulating clay tablets or papyrus, this is as old-school as it gets.Pictures can be saved as either PNG images or text files.
