What is Shimeji-ee?

"Shimeji-ee is a Windows desktop mascot that freely wanders and plays around the screen. The mascot is very configurable; its actions are defined through xml and its animations/images can be (painstakingly) customized. Shimeji was originally created by Yuki Yamada of Group Finity (http://www.group-finity.com/Shimeji/). This branch of the original Shimeji project not only translates the program/source to English, but adds additional enhancements to Shimeji." - readme.txt
