Abstract
This paper discusses the development in Tk of a collaborative browser
for scientific image databases. The browser, known as the
``neighborhood viewer,'' allows groups of neuroscientists to explore
systematically a large collection of brain images. The paper
discusses the application, its development, and a set of lessons
learned during development. In particular, it shows how constraints
and distributed constraints simplified development, discusses the
implementation of a wavelet-based image format, and draws lessons
about engineering experimental, evolving systems.
