I love Dolphin too. My wacky gestures are in this article, written by me after about 2 weeks using Dolphin http://neatandclean.wordpress.com/dolphin-brings-out-the-kid-in-me-and-the-productive-adult-in-me/
I find myself using the custom gestures much more often than the voice command, which sometimes mishears me. Super tabs, so easy to close and switch. Their support team is nice too.
