For Christmas my husband gave me a new lens - for my iPad!! I didn't even know there was such a thing and I'm very excited about it. It has 4 options in all - 2 macro settings and a wide angle. And this one is obviously the Fish Eye. I haven't manged to find enough time to play around with them yet so that I can see what they can really do - but it is on my list. Sort of like, ahem, putting away the Christmas decorations..... :-)
