Well, here's one answer.
Haroshi makes his art pieces recycling old used skateboards. His creations are born through styles such as wooden mosaic, dots, and pixels; where each element, either cut out in different shapes or kept in their original form, are connected in different styles, and shaven into the form of the final art piece. Haroshi became infatuated with skateboarding in his early teens, and is still a passionate skater at present. He knows thoroughly all the parts of the skateboard deck, such as the shape, concave, truck, and wheels. He often feels attached to trucks with the shaft visible, goes around picking up and collecting broken skateboard parts, and feels reluctant to throw away crashed skateboards. It’s only natural that he began to make art pieces (i.e. recycling) by using skateboards. To Haroshi, his art pieces are equal to his skateboards, and that means they are his life itself. They’re his communication tool with both himself, and the outside world.
