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...

Yes. I found it and it was implemented at work with great success on April 1st... We told people that there was probably a crossover cable somewhere along the line !

Users will believe anything their admins tell them... Technology is indistinguishable from magic for most people, including researchers. ;)
