I believe that everyone of you know the ending song from Suzumiya Haruhi no Yuuutsu, Hare Hare Yukai. There are many Hare Hare Yukai parody videos, but this one is particularly well done, and it is also the first Umineko one. I, a big Umineko visual novel fan, was very excited of it.
It was made by an artist called Pokiko. You might want to take a look at his pixiv account, too. He has some nice pictures there. But you need to have a registration to view pictures on pixiv. A nice explanation for those who cannot read Japanese can be found here.
