TimeRuler

TimeRuler is a time-space measuring tool, using light-painting technique. The little box in my hand have several orifices with LEDs mounted inside, which are blinking rapidly. The pictures were created in a dark room with long exposure. During the exposure I triggered a flashlight with a remote control.

If you wish to create a TimeRuler than you can check my instructable.

If time will be on my side, I plan to make some more sofisticated time rulers, for practical use as well.
