If you want to make Time Lapse with your GoPro Hero3 or SmartPhones a little more interesting you can add motion. Simple motion can add an entirely new dimension instead of your basic static shot, and this can be done without complicated rigs. With my iPhone i'm using iMotionHD & with my Android phone i'm using an app called DroidLapse. Here's a quick clip (below) I did while out in Monterey, CA using my Samsung Galaxy S4.
The easiest motion is panning, and although there are ways to build DIY contraptions with Egg Timers, today you can find a variety of off-the-shelf versions for under $30 dollars.
Rotating Panning For Time Lapse
This product is essentially a redesigned Egg Timer as you can still hear ticking and even rings a bell at the end of it's travel. It does offer a female 1/4 thread under the base for a small tripod, and a male 1/4"-20 stud to mount your camera. It is designed for small compact cameras and smart phones, and will rotate 360 degrees in 60 minutes.
You can find this product via eBay (click here).

If you want something that pans slower, the Flow-Mow product states it takes 120 minutes (2 Hours) to rotate a full 360 degrees and even shows that it's capable of supporting a small mirror less camera (found here).
