Actually, ‘PictureBook,’ the name Hans had given the software, was being used for that beta system at Hannover airport. After five weeks without a holiday, most Germans were desperately in need of a break and didn’t much care where they went, so long as it was hot. The holiday ‘vending machine’ let the customer choose the destination at the airport – incredibly What PictureBook had, but our estate agent system did not, was an architecture based on hyperlinking, the technology which, in later years, became a fundamental component of the World Wide Web.

Rather than continue working on two separate software packages, Stephen and Hans decided PictureBook should become a joint development shared between the two Digithursts.

While Digithurst GmbH was moving away from Visual Basic as a programming language, Digithurst Ltd had stopped using C in favour of C++. PictureBook, therefore, became our first software to employ an object-orientated architecture. One of the important features of PictureBook was the dynamic ordering of information. The author could create pages containing moving video, text and static images, then design a template page that acted as a container for information defined when the publication was accessed by the reader.
