Have you ever thought what could be done with 1$ ? Well ,obviously Apple has for iPhone users. They probably thought an iPhone user could only make Origami with such little money and they made this application.
In the iPhone’s Dollar Origami Application , 50 different Origami models ,which you can fold with 1$, are illustrated step by step . If you are an Iphone user who would think “it is only 1$” then you can download the application from here.
