This may take a lot of thinking on the programming side, but I think it might be worth it.
One thing I see with voxelmotion is that it takes a huge amount of time to make each "frame." This becomes really apparent when one thinks of large builds with tons of moving parts, including organics. I would love to see a very large dragon or robot or something move in complex ways (imagine a fairly large dragon flying around Meridia). I would love to see a discussion on if there is a way to take a minecraft schematic, upload it to a 3rd party (or a VB created) 3d modeling software, and make the motions there. Then the new voxelmotion schematic could be uploaded to minecraft.
