One of the tricks you can do on the C64 involves manipulating the video chip into reading the graphics data at an offset from where it's usually located. This allows you to scroll the display horizontally, and the trick is called VSP for Variable Screen Position. However, some machines crash when you attempt this, and the reason for that has always been a mystery. Not anymore.

Fascinating.
