This animation is based on the standard Sierpinski triangle. However, instead of using 1/2 as the contraction factor (the new point is 1/2 of the way from the current point to one of the corner points), the factor is varied sinusoidally over the range 1/3 to 2/3. This gives the difference between the overlapping triangles and the dusts.

While it appears that the animation is 3D, it is really 2D. The corner points move around on 3 separate curves, giving the appearance of twisting and turning in flight.
