%X During the development of a ray tracer on a Meiko Computing
   Surface, problems with poor flexibility of configuration and
   slow software development were encountered. In order to
   overcome these difficulties, and in order to facilitate
   experimental programming on the Meiko, a system to support
   an object\-oriented style for Occam\[rs] programming was
   developed. The aim was to create a set of library modules
   that would allow user code to be quickly developed and
   integrated into existing programs, to support better
   debugging facilities than were currently available, and to
   allow program design to be based on a more flexible and
   dynamic model of concurrency than the process modelThis
   system has been rewritten in order to introduce new features
   and to take advantage of the availability of C. The new
   system is described, with the emphasis on how experience
   with the system influenced its redesign, and on the details
   of newer elements such as the improved facilities for
   monitoring and debugging.
