In Japanese festival, various masks are sold at stores. Children enjoy festivals by covering those masks. Among those masks, the mask of the fox is one of the traditional one. The foxes are enshrined in the Japanese shrine as spirits. In my project, I made a fox mask that can change the picture freely. About 530 full-color LEDs are used on this mask. I can switch images displayed on the fox mask using a microcomputer (Arduino). Since you are supplying power with a mobile battery, I can walk around the venue with this mask.
