Before the holidays Empower released a screensaver but I was waiting until they were officially released to mention them. They have now released 4 different screensavers with 3 showing animated screens and the last showing your remaining battery power. There are both free and paid versions of the animated screensavers but the free version occasionally shows advertisements for Empower products.
You can find the screensavers at these links below in the store. The paid versions go for $2.99.
