Space Invaders piggy bank is fun

Savings is always a good thing, especially when its done Space Invaders style and that too with the help of the Japanese. Takara Tomy is responsible for this retro version of the classic tabletop Space Invaders game. It's the best type of piggy bank ever. One of its best feature is that it is very similar to the original in looks and has an LCD screen that acts as coin counter. It takes only about 100 yens ($1) to light up the screen and add an invader to the tally. You have to empty out the machine after 80 coins and start over. Can you think of a better way to save some loose change in these crunch times? I certainly can't!
