In reply to beardy mike:
> A serious suggestion for you, could you design an app which would visually check a knots topology to ensure it's been tied correctly? Might be some way of pulling in revenue from rope manufacturers who want to be associated with it. Had thought about trying to work it out myself but I have zero clues about apps and programming and well, life...
Oddly, a non-climber acquaintance of mine contacted me yesterday having skim-read the Rockfax VRS item, worried that we need to make sure we covered ourselves from a liability point of view. Whilst I obviously delighted in pointing out the date to them and precipitating a facepalm at their end, the point remains. An app like our joke one, or your knot checker, would come with serious liability questions.
That said, I don't think I would ever want to make a knot checker. That sort of thing is better left for people to get right themselves!
