Vocaloid!!

Just few days ago, i found few pictures that are very unique. Then, i go around to search for that info of that anime( i thought is an anime). Through some of the pictures i found, i realise the character in the picture is from 'vocaloid' . I bet no one know much about vocaloid other than the japanese. Vocaloid is a singing synthesizer application software developed by the Yamaha Corporation that enables users to synthesize singing by typing in lyrics and melody.
There have been 2 products out (vocaloid 1 &2). Among all the character inside, i prefer the twins..they r from vocaloid 2. Now i 'm inserted some pictures i got..Those pictures really unique, most r artwork of someone. i got all from japanese sharing web. Those web got a lot of this kind of work. oh ya, vocaloid also got some song n music quite nice. One of the song i like is magnet.
