Ah just returned from my citytrip to London. Glad there is already a forum topic for this challenge
. Also good to see that criple_ripper actually solved it! Congrats!
I hope you will all like this challenge, although it might prove difficult, everything *should* be logical. Personally I've never seen this anywhere before and probably many of you neither. So..
I wish you all best of luck. Please let me know if you liked it when you solved it.
