Quirky (http://www.quirky.com) has released PowerCurl, an US$7.25,
clip-on cord wrap for Apple’s 60W and 85W MagSafe power adapters. It
wraps both cords (plug end and MagSafe end) around the device and
allows for easy and quick cord wrapping.

The included clip enables the plug end of your cord to clip to itself
just like your MagSafe end does. Also, PowerCurl elevates the power
adapter off the ground or desk for better air circulation and cooling.
