These styleframes/storyboards were made in a day using C4D. Ok, well almost in a day. Everything was done in one day, except for the last (alternate) style frame.
The pile of letters was made using a Cloner Object, then ran a MoDynamics simulation until the pile exploded the way I wanted. Then it was just a matter of simple keyframing the exclamation mark in time with the beginning of the explosion.
Keeping it simple.
