The Monkey Kit (US$69) from Octa is essentially a long, posable tail for your iPad plus a small handle accessory. Like a monkey's tail, the Monkey Tail (also sold separately) allows you to hang your iPad or merely provide support when propping it up. While not everyone will have a use for the thing, the Monkey Kit might come in handier than you think, whether you appreciate prehensile tails or not.
Design
The tail is a flexible metal neck sheathed in nearly 3 feet of grippy silicon, with a locking mount on one end and a rubber tip on the other. When you attach the Vacuum Dock (which should have been called Monkey Head, but I digress), the dock attaches to your iPad using suction.
