This is a shell script that grabs a frame of video from the system's video input, and then uses some PBM filters (chosen at random) to manipulate and recombine the video frame in various ways (edge detection, subtracting the image from a rotated version of itself, etc.) Then it displays that image for a few seconds, and does it again. This works really well if you just feed broadcast television into it. Written by Jamie Zawinski; 1998.
Dit is eigentlik in shellscript wat in videofreem "pakt" op in systeem mei in fideoyngong, wêrnei' t it in pear PBM- filters brûkt (willekeurich keazen) om it fideofreem op ferskate wizen te manipulearjen en opnij te kombinearjen (rânedeteksje, it ôfbyld ûntlûke fan in draaide ferzje fan himsels, ensfh...) Dêrnei wurdt it ôfbyld in pear tellen toand en dan begint it wer fannijs. Dit wurket goed as jo it televyzjeútstjoerings jouwe.
