Each stack was created by a student at Joseph Kerr Middle School using HyperStudio 3.1 multimedia authoring program (Roger Wagner Publishing, Inc. at http://www.hyperstudio.com/).
To simplify playback on the web, GifBuilder 0.5 (http://www.prismagroup.ch/tucows/mac/files/gif-builder-05.hqx by Yves Piquet, previously available at piquet@ia.epfl.ch) was used to create a simple GIF slide show. Please contact the publishers for further information regarding these applications.
