I'm new to presentations with LaTeX; can the Beamer class be used to create flexible page layouts, such as shown below (yellow boxes will be filled with either images or text)? Each page may use a different combination of these yellow boxes, except the leftmost one always stays.
I would appreciate any hint to get started. I have the manuals for beamer and TikZ & PGF.
I am ready to spend some time customizing a template and defining commands if the end product will be reasonably flexible and easy to use.
