Do you enjoy butterflies? If you answered ‘yes’ to that question, then you might find yourself intrigued by a new, free, and rather conspicuously-named jailbreak tweak dubbed ButterflyEffect by iOS developer Pixelomer.
At first glance, ButterflyEffect causes animated butterfly-themed sprites to flutter over the top of your Home Screen and Lock Screen wallpapers. These animations traverse your screen from the bottom to the top and move slowly enough to be noticed, yet fast enough not to get in the way of your wallpaper viewing pleasure.
