In 2002 I developed a Java computer program called UltraKiss that implements the Kisekae Set system, KiSS, a Japanese graphics system originally developed to facilitate costume changes on virtual dolls. Curious about KiSS? Check Wikipedia.

Now, with Webswing technology and modern HTML 5 browser support, this Java application can run on my web server and be accessed from your browser. You can run this application online without having to install any software on your computer.

October 1, 2025. Webswing informed me that their licenses are not valid for open source software. Accordingly I have terminated my evaluation of Webswing.

I plan to develop an equivalent server based solution for UltraKiss browser access using open source web server software. This has the benefit that I may be able to support MIDI sound on browsers that have appropriate capability; a KiSS service that was unavailable through Webswing. Contact me for further information.

In the interim download and install UltraKiss from GitHub.

The source code for this project is available on GitHub under project Kisekae UltraKiss. If you are interested in contributing to this project please contact me.

Using UltraKiss

To access KiSS sets available on the Internet at OtakuWorld or other sites use the File-Open Portal menu command to open the UltraKiss Portal and click on a link. To open KiSS sets available on your computer use the File-Open menu command.

For assistance with using the UltraKiss Integrated Development Environment tools use File-Help to refer to the UltraKiss Help documentation. For developing KiSS sets refer to the KiSS specification and the FKiSS command syntax and the Tutorials included with the UltraKiss Help documentation.

For further information and history regarding UltraKiss see my mad science blog post UltraKiss and my posting about my historical Kisekae Sets.
