By using only storyboards and behaviours Gavin Wignall has created a cool 3D particle effect.
Each element (circle) has it’s own storyboard that uses the
projection properties to spin it around in a 360 degree fashion on it’s
X axis. By increasing the centre point value of the Z axis we get a
larger radius.
On top of that each element is offset by 30 degrees on it’s Y axis,
this allows all the elements to form an imaginary sphere. I have also
set the storyboard durations to different lengths to allow a chaotic
feel to the animation.
