MMDEngine

One day, you happened to open this webpage — and a cute girl jumped right into your computer. She's been living there ever since,. She loves sitting on the taskbar swinging her legs, or leaning over the edge of a window to sneak peeks at your work. When you're busy, she'll quietly keep you company, occasionally tilting her head and staring curiously at your cursor. But the moment music starts playing, she perks right up and starts swaying to the beat. When there's nothing to do, she wanders around your desktop just to catch your eye. Drag her off-screen if she's in the way — but the moment your mouse gets close, she'll pop back out and make a face at you. And at some point, without even realizing it, the first thing you do every time you turn on your computer is look for where she's hiding today. [About MMDEngine] MMDEngine is a lightweight desktop pet app that brings your favorite virtual characters to life on your Windows desktop.
