Odd that this has take so long to hit the main stream markets. I received a key fob/ charm like this a few years ago. It was an ad for some consumer grade Nikon camera. I thought it was quite clever, the solar cells on the sides will switch an LCD screen dark about once a second giving the impression that the image under it itself is flashing. The price is fair, $9US each. I want the Doraemon one. 🙂
