This 3d animation tutorial shows how to make Advertising Hoardings show random images changing over time. I use a single sequence of images resorted to an apparent random order, and then seven versions of this sequence starting at various start points.
I start each version seven seconds further into the sequence than the earlier version. In this way (and the fact that the sequences are changing quite quickly, and distributed over the screen it will be very hard for the eye to spot that the sequence is not random!
