I went to a Performance Sails sailmaking/trimming clinic yesterday and noticed they used Accumeasure to measure sail parameters like draft, twist, etc based on a photograph.
That is not really that special since you can download it free from the North website.
But what is special is that they just ported it to an iphone app so you can measure sails right on the beach!
I think this could be really usefull for registering what happens to a sail over the course of its competitive lifespan.
