Yes, I also remember. We discussed the security of such visual patterns. In theory it was easy to say that "knowing the pattern type" it would be easy to retrieve the private key.
You have a point here, and I am glad that it's working. This will be interesting to see how many users are trying this and how long it takes to solve this. I surrender after my first try which was no difference than some users tried above LOL
Good luck to all.
