Hopefully we will have some new ultrasound pictures to post later tonight. I hope they are the 4D, but we are not sure what they will use today. We keep getting asked what is the difference between the 3D and 4D, and the answer is motion. 4D is like a video in 3D. I was able to get one of the smaller clips uploaded so everyone can see what it looks like. As you can see, Spencer has a pretty decent right jab that he throws at Bonnie's insides... The clip is big (2mb) and may take some time to load, but its pretty cool to see the movement... Click here to see it.
