My friend Danny Visser asked if I could disintegrate him (in Apple Motion, not in real life) so I gave it a try. Note that this is a real disintegration of the source not a fudge that uses only particles. Many thanks to Danny for the idea and the footage (www.davios.nl).

And NOW see here for a simpler tutorial that turns this effect into a transition you can use in FCP: https://youtu.be/_wq_Cm0JEcM
