Sometimes you see people placing a sticker over the iSight camera on their MacBook's such that no one can spy on them.
This might seem ridiculous, but from a previous answer it is clear that it is possible to activate the iSight without activating the "hardwired" LED as well. It was first thought that this was only possible with older models (as shown by this paper), but this article mentions that the FBI reportedly can do this to newer models.
Besides that, I just found that the Dutch head of the cybercrime department officially advises (link in Dutch) to cover the webcam lens.
Now the question:
Are there any elegant solutions to obstructing the iSight lens, besides using tape? I don't want to use tape as it often leaves a residue and looks a bit "meh".
