WHAT IS KiSS?
If you want to know what KiSS is, here is what Otakuworld says about it:
"KiSS, the Kisekae Set system, is a fun and easy paper doll game for computer users.
KiSS takes its name from the Japanese term kisekae ningyou which refers to playing dress-up with dolls.
The KiSS paper doll game allows you to load any of thousands of KiSS paper dolls on your computer and
dress them in different clothes by using your mouse to click and drag the clothes."
Here's a little example how KiSS works (only works in internet explorer). It doesn't have all the effects of KiSS, but it gives a good impression about it. I got the Hello Kitty base from "The Smiley Box". Please don't steal or copy this! I made all the dresses by myself.
All you need for playing with these dolls is a KiSS Viewer.
