I saw this little gem at a festival two years ago and was quite excited to find out it is now on iTunes. I watched it again and now have even more appreciation for it. The special effects aspect is not the selling point here. It's the story and the acting. Fay Masterson turns in a subtle and touching performance as a woman sinking in her own insecurities. In 20 minutes, my heart was in her hands. Linda Hunt's narration is ethereal and haunting. An excellent short that deserves a much higher rating than it has here (though I suspect the rating system is flawed or broken).
In addition, the music is simple and dreamy enough to evoke the appropriate moods. If you get it from iTunes, be sure to get the HD version as the visual effects degrade with the regular version.
