In all of about 5 seconds you can make a nice, sturdy stand for your favorite electronic gadget.
This is a greatly simplified version of petrov's instructable which I thought was clever but too fancy.
Step 1: Parts
All you need is two binder clips: a large one and a smaller one. I had a 1.5" wide one and a 3/4" wide one, so I used those. You can substitute a slightly wider clip for the smaller one and perhaps a bigger one for the big one, but don't use a smaller big one. We need its size for stability.
Step 2: Quick Two-step Assembly
Clap together the smaller clip's hands and then bend the body upwards. You'll have to hold the arms, or the top one will flip open. Insert the small arms into the big clip's jaws, but don't insert them all the way; you want to create a little crevasse for the edge of your iPhone to rest into.
Step 3: Seat It and Enjoy
That's it. You can now view your iPhone at a comfortable angle. The stand supports the iPhone vertically too (no photo, soz) and is quite rigid. Make several and keep them at home, work, and on your backpack carabiner (see the last step).
I'd also recommend memorizing how to quickly make delierium's business card stand. It comes in handy when you're in a bind (pun intended).
Step 4: Portability
Since assembly is trivially easy and there are only two small, lightweight parts, you can carry the stand around with you everywhere. I've attached mine to a backpack carabiner.
