Any possibility to measure the 'hardness' of landing? A hard landing would be interpreted as a failed catch and generate extra dumbass points
About the server, I thought about it but since it's totally open source, it would take 5 minutes to receive a 376294km entry from some funny guy!... Unless we had some sort of compiled version with crypto.. and even then.. someone...
Now. about measuring the 'hardness' of landing, it is totally plausible! I also had that idea.. but well.. maybe for v.2...
Another things in mind are:
"Sweet mode" where it only counts if the phone lands on the same direction it was before taking off
Check if there was acceleration to generate the flight in order to make life of skydivers a little bit harder
Welll... the accelero picks up acceleration, not velocity. Ideally acceleration is zero through the whole "journey". Since the accelerometer is inside (and fixed to) a heavier body it in fact suffers "accelerations" from within the phone itself (like when it is spinning) but that is very noisy...
Comming back to the acceleration thing. Assuming that the phone does not rotate, why should be the acceleration constant to zero? I think RDJEHV was right. It is the rate of change of the velocity. If you throw your phone straight into the air, it gets slower and slower, until it reaches its highest point. There the acceleration should be zero, i.e. for a moment the phone is weightless. That is precisely what happens during a parabolic flight http://www.experiencezerog.com/parabolic.cfm
Edit:
Nevermind, you are right. The acceleration should be constant to 1G, correct? I think I got confused

Umm, no. The acceleration will be constant - 1G. What other force is acting on the phone in mid air? A parabolic flight doesn't actually experience zero-gee, it just feels like it - the plane is actually accelerating downwards at 1G.

Well.. you should all try accDisplay since physics are not helping. The reason why the phone's accel. readings are all zero (and not 1g) is because all the phone parts (including the accelerometer's internals) are (de)accelerating equally. Accelerometers measure acceleration differences relating to "free-fall". Wikipedia might help
For example, the ISS "feels like" zero G (and indeed a accelerometer there will read 0) only because it's indefinitely falling towards earth: orbiting.
Well.. we could go on explaining and giving lot's of examples but really... wikipedia sometimes help.
I really suggest that you (the ones that are still getting how accelerometers work) install accDisplay (extras-testing). With this tool you can "record" the accelerometer's readings and playback slowly and really see what happens.
Well, at the top of the flight, the acceleration is zero. If there is a way you can detect this with the accelerometer on the phone, that would be the moment to take the picture.
I don't know how the accelerometers work on the n900, but that's the main idea.
