Ok, this falls into the category of “both neat and useful”.
Per the cool cats at Mac|Life, Studio Neat has released the Glif+, a deluxe trifecta of contraptions that keep your iPhone securely mounted to a tripod. The pack contains the original Glif, the Serif, and the Ligature. You can use the kit with a Joby Gorilla Pod or a regular tripod meant for your DSLR, or you can turn the Glif+ into its own little tripod. The Glif+ retails for US$30 and is now on the Studio Neat site.
Take a gander at the video, which shows the Glif+ in action.
