Update: I am working on a port of this to AROS, rewritten in ISO C90 using AROS libraries, and compiled with AROS GCC.
A SourceForge page has been created for this project at http://sourceforge.net/projects/arosamosabk
An ISO file is also available on SourceForge for easy use with e.g. VMWare or VirtualBox.
An image corruption bug has now been fixed. Grab the latest build from SourceForge, now with added icons.
The latest release fixes a bug with the window borders, and adds many more features from the Java version including image zooming and spacing.
Some screenshots of this running on Win32 hosted AROS, Icaros Desktop and AROS Broadway are on the SourceForge page.
Updates are pending on The AROS Archives and Aminet.
