Exercise 6.1 To fade out progressively, reduce the opacity of the logo layer, merging each new layer with an unchanged background. Copy the resulting layers in reverse order.
Exercise 6.4 A solution is given in The IWarp Tool.
Exercise 6.6 First, build the flickering logo, as in Exercise 6.1 or 6.2. Next, build the animation with the Move Path tool. The logo should pass horizontally from one side to the other during the full animation. Successive layers are taken from the first multilayer animation, if you choose the STEPMODE LOOP.
