Ya like sliders? Lame. Because guess what little buddy? No one cares or clicks.
Let me lay some science on you – 90% of sliders on the web are pointless fluff. Google it. But, on a purely presentational level, a nice little background image animation certainly has merit. Plus, considering the wide-ranging support for css animations (keyframes, transforms, transitions), it’s easy to accomplish this UX pattern with a purely css approach (no javascript).
