It's achieved by photographing each frame with a really long exposure (in this case, 5-15 seconds). No CGI on this. I didn't have a remote control, so I had to run back and forth to press the shutter release button and draw the designs with a little LED... in pitch black. Then, I'd inch the car forward and do it all over again. Then I got rained on, so I couldn't get all the shots I wanted. Hi. Hope you like it.
