Surely
you have heard of
ascii art?
"Deep Ascii" is a full length conversion of the classic porno flick "Deep Throat". Yep, ascii video - 55 minutes of it (no sound) - 220 megabytes.
The creators chose to remake a porno film because they feature a good amount of close-ups, which convert well into ascii character resolution.
You want to see Deep Ascii online? Bad luck if you have a modem, like me, but here is a url:

Unfortunately, you won't find the source code for the applet there.
