The Networked Stock Market Piggybank

Description

StockBank is a networked piggy bank that displays the current price of ONE share of top tech stocks such as Apple, Facebook, Google, and counts down the current price of one share of the stock depending on the amount of coins inside the bank. As someone drops a coin in the bank, the display shows the amount of the stock share price decreasing until it levels off at zero which means that there is enough coinage inside the bank to buy one share of the stock in the display.When the amount in the bank equals that of the stock, the bank automatically buys a share of the stock from an online broker and the pig blinks on and off to show that it was purchased. When the bank is emptied, the counter resets back to another share price for a top tech stock and starts the process over until the amount matches the price.
