Very cool
That was probably the best done incorperation of Flash and real time video. It was very original and had a good flow to the "story" that existed in the film. The graphics, although most were lines or just video, were not very expressive in themselves, but they were put together nicely and fit very well. The single thing I did not like about this was that some of the transitions between holding a Flash line in your hand and holding a physical object were very blatent and could be easily seen. If I were you, I would have just animated all the lines and not used any live action objects. Other than that, I have no complaints.
This was very well done and one of the coolest live action + animation Flashes I have seen in a long time. It reminds me of Harold and the Purple Crayon. Nice work!
