Oh man, this just unlocked a cool memory - I was in my computer graphics course in college and was trying to write a shader that would generate a wood-grain texture.

I messed something up about it, and must have been pulling from the wrong graphics memory, and noticed That the brown wood didn't have a swirl pattern but had what looked like text in it?

After staring a bit closer, I noticed it was the text that was written to the console in visual studio, I had somehow brought that graphics buffer in to use as my "swirl pattern". I had to sit back and think a bit about how data on your computer isn't always as safe as you think sometimes after that...
