Measurement software using camera!
 

I found a software that someone finally implimented, it involves using a credit card/similar size object, and it has a box object that it imposes over the picture taken, and compares relative to that box (can be shrunk or enlarged using the touch wheel) then a vector line is created to calculate the approximate length.
The only problem is that it needs to be taken at a parallel angle otherwise it doesn't work too well on angled objects.

It requires .Net compact framework 3.5:
It is called DarkRuler. <- *link*

screenshot of it in action, its still not super accurate but does the job

I've commented in the XDA thread on this...it's a really neat idea but the final measurements are off. I think it's because a slight difference in the measurement of the credit card gets amplified when measuring the larger object.

and be careful, someone was saying that you should only use credit cards for measurement and to post up pic n taking the cards info, dumb on the users part imho but it happens.

Oh, I just used a school ID and all the card in my wallet seems to be the same size.

correct, anything that is the same size in length. That's just the universal scaler used here.
