Timduru often have really nice light effects added to his suit :) Combination of long exposure time and flashlight is used. Flashlight will stop motion of any objects that doesn't have light sources in them, like fursuiter in this case. But long exposure time brings feeling of movement to picture when any light sources draw nice colorful traces of light to photo.
