These wallets link with your bank account and get bigger or harder to open depending on your balance.
Proverbial Wallets, a new project from the MIT Media Lab, offers a more innovative way to check your balance daily. The Bluetooth equipped wallets physically transform depending on your current financial situation: The Bumblebee buzzes every time your bank account updates. The Peacock inflates or deflates depending on your total assets. The Mother Bear (pictured) has a hinge that makes it harder to open if you are approaching monthly budgets.
Says the project's developers:
The Proverbial Wallet gives us that financial sense at the point of purchase by un-abstracting virtual assets. Tactile feedback reflecting our personal balances and transactions helps us develop a subconscious financial sense that guides responsible decisions. In addition to providing a visceral connection to our virtual money, tactile output keeps personal information private and ambient.
The wallets are currently a prototype, but will hopefully actually be available soon. Here is a video of them in action:
