Press Release 000204

  Calerga announces new versions of SysQuake and SysQuake Viewer, powerful
  software for scientific visualisation. Through innovative use of
  interactive graphics, SysQuake reveals insights into complex mathematical
  systems.

Lausanne, Switzerland, February 4th, 2000 - Calerga announces today
SysQuake 1.2 for Macintosh and Windows computers, the latest version of the
application which helps understanding mathematics, physics and engineering
and enables improving easily the performance of technical systems.
SysQuake 1.2 is a free upgrade for licensees of SysQuake 1.0-1.1.

SysQuake 1.2 improves even further the ease of development of new
applications. This is especially powerful for scripts which define a large
number of figures for complex engineering projects. In addition, an
integrated help system has been added. New graphic commands have been
introduced. Several bugs have been fixed.

SysQuake Viewer 1.1, the free application for viewing live interactive
graphics, is also replaced with a new version. SysQuake Viewer 1.2 is based
on the same code as SysQuake 1.2. It is available for Macintosh and Windows
computers. Continuing going forward, Calerga announces also, together with
a new prerelease version for GNU/Linux Intel computers, the first
prerelease for GNU/Linux PowerPC computers.

SysQuake is a ground-breaking application for understanding and designing
complex systems by the use of interactive graphics. Interactivity lets the
user manipulate graphics, observe how phenomena are related, and change
parameters to improve the design of a technical device. Understanding how
initial conditions affect a simulation or how the parameters of a feedback
controller determine the behavior of a dynamic system is made much easier
than with the static graphics created by existing software.

SysQuake's powerful, yet easy-to-program computer language opens it to any
kind of application; SysQuake handles the user interface itself, letting
the developer concentrate on the specifics of his or her problem. It is
shipped with applications in the fields of automatic control, analog and
digital filters, model identification, physics, and finance. SysQuake is
not only useful for research and development--its ability to help really
understand the system beyond the graphics makes it the ideal tool for
teaching.

SysQuake Viewer can load "SQ files" (programs for SysQuake) processed by
SysQuake Signer. It offers interactive graphics which help tremendously
understand what the graphics represent and how they are related together.
It can be used as a helper application for World Wide Web browsers such as
Netscape Communicator; when a link to an SQ file is clicked in an hypertext
document, the SQ file is downloaded and opened automatically in SysQuake
Viewer.

SysQuake 1.2 and SysQuake Viewer 1.2 are available immediately. For more
information, for a demonstration of SysQuake 1.2 which lets you try many
applications and even program your own scripts, or for downloading the free
SysQuake Viewer and interact with more than 30 live interactive graphics,
