This isn't the same, but I've an idea in case the boot animation never gets made.
1st, download https://play.google.com/store/apps/d...r.multipicture
for the wallpaper. Leave it alone for now. Now download this zip file
and unzip it and move the folder in it to the root of your sd. Should be /sdcard/Brittany.
Go to the "Set Multipicture Live Wallpaper" as your wallpaper, but first go in to the settings. Click "Common Settings>Picture Source>Picture Folder." Set the Folder Path to the location of the pictures(should be /mnt/sdcard/Brittany). Now change the "Picture selection order" to "Name Ascending Order." Now hit OK. Now make sure "Crop/Resize ratio" is set to Fit to Fullscreen. Now hit back. Disable "Double tap to change picture." Set "Picture Change Interval" to either 5 or 10 seconds(i recommend 5).
Now it should be ready. Hit back, Set as wallpaper, and make sure it works right and shows all 6 pics in the correct order.
Now empty your homescreens, so nothing blocks the pics. Turn off the device and get yourself ready.
Ask her to turn on the phone, "while you're busy" and then when it turns on, get her unlock and pay attention to the wallpaper.
