Motorola is making this available on its Boot Services app on the Google Play Store, inside a folder called "aprilfool". What we won't know until Wednesday, is whether the animation will hang around after April Fools' Day.
This shows the advantages that manufacturers like Motorola and HTC have in publishing their system apps in the Google Play Store. Instead of taking days to roll out an update, those interested can go to the Play Store and merely download an updated app. By the way, feel free to check out the April Fools' boot screen animation by clicking on the video below.
