That's not "Pika", that's just light painting.

You need to set the camera up on a tripod, f/8, about 20 seconds. Take a little LED light of some kind and draw the shape you want in the air in front of you, repeatedly, pointed towards the camera. Because of the long shutter speed, the lines you make with the LED will create lines of light in the image.

There's no such thing.

As for getting your subjects in as well, you can try aiming a light at them while they aim the LED back at the camera. DONT use flash, just use a flashlight.

This my favorite one.. The hard part is remembering where in the air and what you just painted for the next exposure.
