it's a teeny bopper dance video making program. It's a cartoonish 3D world. you can change dancers, clothes, & music can be from CD, MIDI or wav. Called "Dance Studio". You hit keyboard keys for certain moves that were motion captured from pro dancers. There is a music editing / creation program included. You can output the dance you make into a bvh mocap format, which can be imported into Poser. It is a bit unstable sometimes, but that depends alot on the 3D accelerator/video card you use, I believe. I don't know why it isn't more popular with the poser dudes.
