Paul Reuvers is the Director of X-Ample Technology (XAT) in The Netherlands. He gave an overview of his involvement in the Acorn/RISC OS world from the early 1980s to the present day. Apart from developing software for the platform, Paul still uses RISC OS on a daily basis for a variety of applications, including web design for one of his other passions. He has a very keen interest in cryptography (|[www.cryptomuseum.com|]), and is working on an update to the Enigma code machine simulator for RISC OS. He also demonstrated Watermark which creates watermarks on images to prevent copyright breaches.
