In 1988-89, I was a young teenager, I remembered I got a floppy with an erotic picture on my Amiga 500 using the HAM mode which allowed 4096 colours simultaneously. The image was quite realistic, which contrasted with the usual 32 colors graphics. Back then, it wasn't usual to see something looking like an actual picture on a computer screen.

So I remembered showing this picture to some friend, to brague about my computer capabilities, when my conservative grandma entered the room and saw the pictures. She was shocked and started lecturing us on love and sex.
