We used Prezi to create a kick-ass presentation.  The appearance started with a white screen and faded to the circular form of an overhead multi-headed surgical lamp. As the presentation progressed, the lamp became the navigation, with each head representing a different section of the speech.

3d headPrezi is a great tool for creating dynamic, captivating presentations, unfortunately after adding custom flash content, numerous embedded video clips and dozens upon dozens of photos and illustrations, the file became too monstrous for Prezi to handle reliably and we had to switch to Powerpoint at the last moment.

I created a series of 3d illustrations using Sketchup to model the head and illustrator to add captions, shading and other graphic elements.
