Mac Funazimu's transparent memory sticks have a few very special features. They feature colored lights that correspond to different data. A blue light indicates data for documents, pink indicates data for images and green indicates data for movies. When no lights appear, the memory stick is empty.
Whenever these transparent memory sticks are shaken, the colored lights move. Mac Funazimu was insipred by the Japanese revolving lantern in designing his transparent USB memory stick.
