Hello all,
about a decade ago I remember coming across a network prank script that
inverted all images coming in though a NAT (?). People on the local network
would see upside-down images in their browsers.
I don't remember the details, there was some hookup into the NAT (or a
forced proxy ?), some call to ImageMagick to invert the images, etc...
I tried to search for it on google but came out empty handed...

Does it strike a bell for anyone ?
Yeah, planning for thursday...
