Coming from Scott Amron is a money clip that literally is money securing your money.  Two circular steel plates and a thin neodymium magnet are adhered to a bill.  All you have to do is place your valuables in between.  This is one of those projects that I wish I could’ve come up with.  Not sure if I’d pay $12 dollars for a buck and some material to secure my paper and plastic, but the idea is brilliant.
