I like this idea, and the Live Wallpapers are very neat. However, they run much shorter than the actual clip is. For e.g. when I tap and hold on the photo (in the iPhone OR Watch Photos app), the clip runs about 3s. When my watch wakes up, the clip runs about .5s, somewhat anticlimatic. The out-of-they-box wallpapers (like the butterfly or jelllyfish) run much longer when the watch wakes up.
