Get Lippy! is a fun entertainment Application that I built for the iPhone earlier this year (2009).
This silly iPhone App automatically records when users talk into the microphone. Then it trims the sound input and plays back the speech either like a Chipmonk or Barry White: the App enables you to control the pitch adjustment.
You can choose pictures from your iPhone library or take your own on the fly and then select from 4 comic talking mouths that you can resize/reposition to overlay your photos. When the app plays back a recording it animates the lips fast or slow depending on the pitch as it detects audio levels.
New functionality in version 1.1 includes the ability for users to submit their animated recordings to the Get Lippy Gallery and send them to their mates.
Update (4th October 09): Recently I was chosen as one of the 3 minute wonders to speak at Flash on the Beach ’09 conference. My presentation was about the iPhone Development Workflow from a Flash Developer’s perspective. You can see the video and a few more details here.
