I found a pretty neat live wallpaper recently. The free version can light up when a SMS message is recieved and the paid version can be set to do that for all notifications; as far as I know no other difference exists.

That theme is still on the Google Play store at https://play.google.com/store/apps/details?id=com.pimentoso.android.hexagonbattery.lwp
I use this on my phone.
