From the developer:
UltraKiss simplifies many of the technical details of building and viewing KiSS sets. For viewers, UltraKiss displays KiSS sets and lets users interact with the set using the mouse and keyboard. For developers, UltraKiss manages images of dolls, clothing, and many other media objects that are included in KiSS sets.
The original KiSS model defined a special image format called the KiSS cel format.
