(GTKY) What's on your post-it notes?

Time for another Getting To Know You thread!

This time around the question is: Most of us programmers have one or more sticky notes around the frame of the computer's screen. Mine has the OpenGL coordinate system drawn on it (i.e. +y goes up, -z goes yon, +x goes right), and another has the OpenGL 4x4 matrix offsets. What's on yours?

I don't have any post-its around my monitor. Instead, I keep a Word document open with useful information that I need to refer to often. And another (encrypted) document for passwords that I'm likely to forget.

I do keep a few sheets of A4 in front of my keyboard though, for quick scribbling.
