Blue Mountain, an retailer of animated online greeting cards, has an animated birthday ecard that includes a game of Birthday Invaders. The game is just like space invaders except the aliens are replaced by invading birthday party supplies. The graphics in the game are very unremarkable but because the game is contained in an ecard it might be funny as a birthday ecard for a gamer friend. You will need to register with Blue Mountain to be able to send this ecard.
