This is quite a good thing that's been knocking around during Channel 4's 3D week (note to overseas readers: yes this has actually been happening, they've been giving away 3D spectacles in supermarkets and everything): it's a 3D JLS advertisement.
Incidentally, if you've got youir 3D glasses to hand we've created a magical 3D illusion which will 'come to life' if viewed through special glasses.
Incredible.
