Gashi-gashi, I don't know how you made your pictures but they are beautiful! I would like to know what you used in hopes that I could make some as good. If you don't want to say, that's ok. I mainly want to make fun stuff like this.
This is most interesting. I've known Vocaloid and loved them for some years now. But a few months ago I left the states and came to Thailand. The first store I shopped at on my own was Family Mart, and I still go there a lot, because it's closest to me. Sadly, I've never seen anything Miku related there T_T. But when I walk home from class, there's a shop at the subway that sells Nendoroid figures, a lot of them being Miku. One that caught my interest was Sakura Miku. But I'm not a big collector, and I can't really afford it right now, but it's still pretty neat.
It's simple, really. Looks to me like they're using the popularity of animated characters as an advertising tool. Btw the blue-haired one is Miku Hatsune, or Hatsune Miku in Japanese order (the Japanese say the person's surname first), assuming you didn't know. She's a computer program that sings, essentially.
