Highly relaxing, yet addictive...

The music is very nice to have as we color the pages. Everyone enjoys this app: my daughter (3), son (5), my mom and I (58 & 37). We upgraded and now have all pages and color options. The page will reset if it is shaken or rotated, but there is a warning about that (its meant to be a quick-erase, but can be quite upsetting to the smaller artists).
