Just a suggestion to improve the hunt...
Sometimes it is very difficult to understand what is a line produced by a particle and what is the background. I believe that if the background wasn't so noisy it would be a lot easier for us to spot off-center vertices. I don't know if that's intentional or not, but a solid dark background would definitely highlight the lines and make things a lot easier.
Thank you for your attention.

Thanks for the suggestion, @tiago.sartor -- there may be some reason that the background appears the way that it does.
Perhaps a scientist could explain?
