ShootMe is an Android app for taking screen caps on Android devices. It’s very popular, but has been removed by the developer from the Android Market for some reason.
IIRC, it’s said to take screencaps just by shaking your Android device.
Here’s a download link to a ShootMe.apk file. Let me know if it works or not, because I believe this Android app requires ROOT access, which I do not have.
