Here's a fun and simple idea to help spread the idea of bitcoin to your friends this holiday season. Buy or print holiday cards. Then print a public/private key pair on the card.* Get some scratch off stickers from your Office Depot and cover the private key. Give them the cards and tell them it's a surprise. After they give you a puzzled look, have them scratch the sticker off to reveal the private key. Show them how to import the key on a smartphone. Then show them how to spend the Bitcoin on valuable and exciting gifts.
* When QR codes are available for this it will be much easier.
Cool idea, its already being doing virtually,
