Multitasking Gestures is the clone, but does not allow you to swipe between tabs like Zephyr, it only allows you to swipe up to close which is all I really used it for luckily.
You might want to give Swipe Safari a try! It allows you to set different actions to different swipe directions with different number of fingers on Safari. I love it.
