Most of the demos you see involving 'flowing'
colours involve some sort of manipulating of the display list but
here demo master Chris Fox shows that you don't need to manipulate
the Display List at all, in fact you don't even need to use one! No
Display List, no Antic, so how is it done? Ah, that's a puzzle for
you to solve, or a secret to be kept from all but the few. Even if
the secret proves too difficult to discover, type it in anyway, it's
another of Chris Fox's pieces of magic.
