And for those interested, here are the Nodes for the scanline effect:
The Value Node contains the frame number and the Modulo 2 makes the odd numbers 1 and the even numbers 0.
The Y of the Generated Texture Coordinates goes from 0 to 1, so the multiplied version goes from 0 to 240 and the fraction (what comes after the decimal point) is half the time greater (or less) than 0.5 so this gives 240 white lines and 240 black lines, which corresponds with the vertical 480 pixels (the resolution I use is 640 x 480).
