With OLED, once you go black... 😉
Save battery. Keep it static. I did that live wallpaper nonsense year ago on my Nexus One and the novelty wears off. Just eats up battery life slowly and RAM.
I actually like the wallpapers the X had with the polka dots bubbles or whatever like the one pictured in this thread. I like red but then think about chicken pox and pimples...
If I had it, I would go multi-colored polka dot bubbles for awhile before it gets boring or plain black like the old iPhone 2G when we couldn't change our homescreen wallpaper until iOS4.
I use ZEDGE to find wallpapers. It appeared on Android first but was happy when iOS has it. I also have apps for 3D parallax wallpapers. A novelty...
Just going to use the wallpaper I have on my SE. Nearly black but with a hint of green, blue, and yellow on top and bottom. Very subtle and isn't distracting.
