Antics
Antics was a great tool for draging and dropping 3d content which would self animate. Unfortunately the company no longer exists but the software still works. MovieStorm, DAZ and other solutions are viable options now? While the finished product is not fully photorealistic, it can really help to develop one's shots and organize logistics. It becomes a living storyboard.
Antics competition entry
I put this together for an entry into an Antics competition which had to make use of their "medical pack" of items. It didn't win but was in the top ten somewhere.
Pre-viz sequence
I did this as a spec pre-viz sequence for the 1st episode of "My Own Worst Enemy" TV series.
Aristotle
Another spec sequence based on a friend's script ( Alan Taylor ) which I used to practice using the software.
