Kept noticing my Compaq Portable's still showed an afterimage in a pitch black room... decided to take a long exposure photograph of it an hour after turning it off, and was really impressed by how much was still readable! You can even see the speed of the serial port I was using! #retrocomputing

Now it's been almost 3 or 4 hours since I transferred data over serial and the faint ghost of the serial port and speed are still visible here. I had no clue the persistence lasted this long. Also there's so little light that the image just appears solid black on my camera now!
