Another way to do Navigation...
We often have threads about Navigation and how (if?) to do it.
I was asked to produce some navigation yesterday for a website - http://youtu.be/6EE2HxISa44
Although built in PowToon (not Articulate), this gave a nice counterpoint to the classy website. We tried to keep to the same visual styles, colours and fonts, and only a few "cartoon" effects, and it worked very well.
I guess what I am saying here is that breaking the mould of the main course style, albeit gently, is another way to introduce some visual interest, and it could work for Section starts/ends, or anywhere where you want just to add a little interest and emphasis.
