Just received a delivery from TawnyT and it's perfect!
This is in response to the crushing news (though obviously I'm over that now) that Simone 5 was not for me. 
Part two here; Delivery II
So, there is a knack to this one. If you can pull it off you get to see the picture in 3D. You need to make your eyes go 'cross-eyed' if you can. You should then have three or four pictures of the cage, not two. Three here is the magic number; once you have three (This may take some practice and some trial and error.) Stare hard at the middle image, make sure it is aligned and try to get it to focus. If you can, the image should resolve into 3D. Good Luck!
