The VOCALOID video that has attracted the most attention among the Japanese fans right now must be "MMD Collaboration: The MMD Project for the Dr Morinomiya Anime Project, 'Honjitsu Eigyo-Chyu PV'".
In April 2008, an ex-animator Yucca-maman decided to make an anime PV for KuchibashiP's Hatsune Miku song "Honjitsu Eigyo-Chuu (We are open today)". She drew a storyboard for the PV and uploaded it on June 27, 2008. Then, all of sudden, a volunteer group of MMD (MikuMikuDance, a freeware animation program) creators made a MMD video based on her storyboard and posted it on Nico Nico Douga yesterday.
