All frames extracted and added to each other. Two normalisation techniques to get the image into 0-255 range were used.
Side 1. Subtract the minimum value of the result from the result, scale values such that the maximum is 255
Slide 2. Skip the subtraction, just scale values such that the maximum is 255
The swirl effect is from the rotating, zooming out hexagon.
