Model Koyuki Sato displays Japanese toy maker Tomy's new gadget, an 'evolutional' violin called 'Evio,' during a press preview in Tokyo Tuesday, April 15, 2003. The string-less electronic violin can be tuned if the player cannot actually play the instrument with a built-in optical sensor. With the motion of the bow, the melody is played from a cartridge box. Eight melodies are ready and the maker plans to add up to 20 in this year. (AP Photo/Chiaki Tsukumo)
