A fun software. Or Art? Whatever, play with it if you have Quicktime and a camera.
The program has some controls. Use 'C' to switch between square and character mode and 'F' to change whether 1 or 0 is used for bright areas. To slow down the scan line use 'up' and 'down' cursor keys. To change the brightness threshold use the 'left' and 'right' cursor keys.
For me it has worked as an example how to use Quicktime for Java to get images from a camera. The code is also available on this local subversion server. Check out

Ant build.xml is included. However, you might need to change the place where your QTJava.zip file is located if you are not using MacOS X.
