AsciiCam generates ASCII images in real time from whatever your camera is pointing at. Choose from black and white, primary colors, or full colors, take pictures, and share them as images or HTML. You can also create ASCII versions of pictures in your gallery, and optionally have ASCII versions automatically generated every time you take a picture with the standard camera app.

AsciiCam is completely free and open source.
