We used the simplest way people use to explain new concepts: By use of hands. We explained the new system of discounts with five simple 'handy rules' based on illustrated hand symbols. The technical possibilities of a CD-ROM allowed for an interactive and animated presentation: the effect of the five main parameters on the fare is shown by a little animation, the user can even click on the animations to take control over the animation sequence. A quiz at the end of each parameter let's the user check, whether he understood the rule of the discount.

Around 1.2 million copies of the CD-ROM were duplicated and distributed in train stations in the whole of Germany. The CD-ROM helped a great deal explaining the new pricing system, and according to the client, this was a great piece of work to transfer the campaign idea of the 'handy rules' to the interactive medium, making the visualisation of the print creative more alive.
