We are pleased to announce the first public release of the HypeDyn hypertext fiction authoring tool: http://www.partechgroup.org/hypedyn.

HypeDyn is a procedural hypertext fiction authoring tool for non-programmers who want to create text-based interactive stories that adapt to reader choice. HypeDyn is free to download and open source, and runs on Linux, MacOS and Windows. You can download HypeDyn from http://www.partechgroup.org/hypedyn/download.html.
HypeDyn was written in Kawa Scheme, http://www.gnu.org/software/kawa/.
As part of our ongoing research, we are interested in how people use HypeDyn. Please let us know at hypedyn@partechgroup.org if you are using HypeDyn and would like to tell us about your experiences, in particular if you have made any changes to the code.
We are also interested in having authors take part in a more detailed study. If you are interested in helping with this study, please read the details at http://www.partechgroup.org/hypedyn/study.html.
Note that downloading/using HypeDyn does not require participation in the study.
