I use [LICEcap][1] fairly extensively when answering questions on stackexchange - its a VERY intuitive tool for making gif-based screen captures 

![LINEcap gif example][2]

You open the application, select an area to record, choose a filename to save it, and do your thing so it can record.

However, this is Windows and OS X only - I've occasionally toyed with using a Linux VM and capturing the VM window, but I'd like a *native* alternative that would record a gif the same way.

What could I use?
