Can't remember which version of Excel it was but in the late 90s there was a combination of cells to click and you could access a 3D realtime "credits" with the names of all the programers, like a flyby through a flat landscape and blocks with the names mapped. At the time I was working in game development and all the programmers shook their head saying "No wonder MS products are so slow! They've got a bloody rendering engine in there!"
