Use illustrative aids in every phase of trial.

People understand information easier and retain it longer when things are explained to them using illustrative aids. Use this to your advantage. In every phase of trial, use illustrative aids: maps, timelines, photos, charts, whatever will help drive your point home.

Powerpoint works great for this. However, if you need to manipulate the illustrative aid in real-time, there is nothing wrong with an old school white board or a pad of paper on an easel.
