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

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.
