What Fliopograph does is display two high definition photographs on a plastic card that change based on which angle it's viewed from. It seems almost like the cards are a mini computer screen since it refracts light. This means you can essentially have your marketing message and then perhaps have a large URL address on the 2nd view.
On another note, the 3D trend sure does seem to be taking off. I recently saw a commercial for 3D toothpaste and realized they've taken it too far. Imagine that, toothpaste in 3D, i.e., real life toothpaste because you can see it from all sides.
