Introducing Big Buttons
Here's a video demo of an iPhone app I've been working on called Big Buttons. The idea behind it is that it allows you to control your mac with your phone.
I've made a bunch of buttons that do a wide range of things, but users can also make their own buttons using AppleScript.
I have a modest budget for a designer to help me make Big Buttons beautiful, so email me at mailto:firstname.lastname@example.org if you're interested in helping out. Also email me if you want to join the beta.
