How to frost a cake (in under 25 seconds)

I'm a long time Mac lover, but a recent iPhone owner. One of my favorite app discoveries is Motion Pictures - it makes it really easy to take timelapse movies. 

Here's my favorite movie - filling and frosting a cake in 22 seconds (decorating took a bit longer:)

 

The finished product: 12" Abby Cadabby vanilla bean cake with raspberry filling and vanilla buttercream.
