Thanks for you inputs, sorry I've been really busy and did not have time to answer earlier
but your comments are very valuable to me. Just a few comments:
- Flip speed could be increased, I agree that a VERY important factor.
- Battery life, honestly I never tested it but there is no refesh when page isn't moving so I guess effects will be minimum.
- Spine area can be of course hidden, we show it in the video as a demo
