This technique originated from a video clip that Bruce Gabrielle posted on his blog — this video showed you how you can create a triangular table in PowerPoint by either creating a picture of the table itself (which makes the table non-editable) or by creating a picture of the table with just empty cells so that you can place a transparent table with figures or words over it. While both techniques are amazing, I wanted to use a process whereby not only is the table editable, but the ending shape need not be limited to just a triangle. Also, you can use this to hide and show parts of not just a table, but almost anything else including video clips.
