640 frames built in Flash CS5, exported as jpgs, placed into Sony Vegas 15 at 1 frame each, rendered out at 24fps in 1920 x 1080. Then this version brought back in, edited for timing, rendered again, then brought in on two layers, the lower one being over-exposed to white, executing a cross-fade at the end for a transition into the next scene. No sound. For reference, earlier versions are in animated gif format on an earlier post.
Here 'tis so far...it runs about 20 seconds
