Live ASCII video
Capture from Video4Linux devices and render frames into readable ASCII output.
Live webcam video rendered as ASCII art and published as HTML, plain text, or a terminal window.

Since 2001, Hasciicam makes it possible to make live ASCII video.
Hasciicam captures video from a TV card and renders it into ASCII. It can format the output as an HTML page with a refresh tag, as a live ASCII window, or as a plain text file. This lets anyone with a video device and a modest Internet connection publish a live ASCII video feed that can be browsed without plugins, Java, or other client-side requirements. And it can also be printed! It's ASCII Art!
