Just going onto Nico Nico Douga, I instantly noticed, that the layout of it changed! :O
Since I was using the very old version of the player, not the Q version, it was instantly noticeable.
It's called GINZA, and I have to say, I f**ing love it. And "it" is that customizable wall background! There are some really amazing ones in there I can't decide on which one to pick >.< Don't you think it's so neat?
So I hope it's not only a temporary thing like that Z player with the kamehameha's on April the 1st.
*rolls away, amazed*
