A "heads up" for all you BLUE LED freaks

[roadrash]

I got a greeting card (Hallmark) the other day that had a starry snow scene and a little "press here" graphic. When you press that spot, the stars light up and twinkle a bit. Inside the layers of the card, there are 4 BLUE LED's, a switch, and a circuit board with batteries (probably causes the twinkle). It looks like the entire thing could be removed from the paper and applied somewhere else. I'm not sure what the cards cost, but it might be a useful starter kit for making LED accessories. I'm thinking I might make a light to stick under my desk. heh heh

I'll try to find a link to the card on the Hallmark site, once it starts responding again, geez.
