This was seen at the Air and Space Museum in Washington DC. Haha, I wonder if they realized this was going on! It was at an exhibit by the entrance about the International Space Station. If you can't make it out, the screen has a crashed hard drive error - it's supposed to be showing a movie or something. You may have even encountered this error before on your computer. It begins with, "A problem has been detected and windows has been shut down to prevent further damage to your computer..."
On a related note, some interactive displays where you can choose a short videoclip to watch (in one of the inner exhibits) can be slightly glitched up. Hit all the buttons rapidly (hehehe) and it will confuse the computer and you'll see a Windows 98 boot up screen for a second or two. |
