With my final project I combined two works of art to create something new. This bike watch is used as a turn signal for local cyclist. With everyone going towards a greener earth, and less pollution I fell as if this will gain popularity. The watch turns on by motion, it turns yellow with a blinking flash for a right turn. A left turn will also be yellow but the light  doesn’t blink.  This will help cyclist that likes to ride at night.
