I really enjoyed that! I have iStopMotion but have never tried it. Guess it's time to experiment a little.
Nice vid but why would you need to use iSM for $499 if you can do the same with simple iPhone app say, ReelMoments for $0.99 You vid is nothing more than time lapse video.
You can also use iStopMotion Home which is just $9.99 at the Mac App Store this week.
