YouTube user AWEDYSSY found a great way to make items in your item frame rotate! Check out the video and see for yourself. As you can see using some redstone, switches, and torches he has been able to make the item rotate. This would look great in any house! Heck even if you could build a clock, that would be amazing!
In Minecraft 1.8 item frames now give off signal strength and can be hooked up a signal strength decoder to make a quick and easy 8-way selector switch.
