Website http://miku-39.jp/ has now been updated with the addition of a customized music video for Mitchie M’s Birthday Song for Miku. Before watching the video, the viewer has the option of linking in a Twitter account, location information and a smartphone to further enhance the video. For example, the video will show your Twitter icon over your place on Earth as it zooms out to display the many other Miku fans. Linking a smartphone adds a secondary display and also allows flicking flowers, etc. for Miku (and the website keeps track of the sum total). Furthermore, throughout the video, happy birthday messages previously written for Miku by visitors of the site will pop up as well. New messages are still being accepted, too.
