Did you know that you can jailbreak your Olympus software? Once you do that you will be able to use your Nintendo DS to capture timelapse shots with a built-in alarm and triggering the shutter by clapping your hands instead of pressing the button (Yeah I know it is exactly the feature we were all looking for).
You need to install the Open Camera Controller (which is Open Source).
Your camera will now have following features:
* Unlimited AEB
* Sound Trigger
* Motion Sensing
* Sun-/Moonrise aware
A complete description of the software is available here: http://www.hdrlabs.com/occ/index.html
