Being a follower of the blogs and posts that are available here I have noticed that it always pays to keep your eyes open as you never know what you might see when you are out and about that will inspire you. Yesterday I was walking through a hotel when I noticed a really cool menu screen on the internet kiosk that I thought would be really useful in e-learning (similar to Tom's post on the ipad design).
I have tried to re-create as best as I can (I'm no graphic design expert), but hopefully it will help inspire you to try something different in your courses. I have included a couple of different ideas too just using PowerPoints preset 3D shapes.
Hope its of use
