Mind Bender #2 : Solution

Thanks for submitting your solutions for the last Mind Bender.

It’s interesting that most people tend to focus upon what is there – rather than what is NOT there – in seeking out a solution. So, it’s good to see that a number of you don’t place such limits on your own thinking.

Anyway, congratulations to those of you who picked it up quickly. And maybe I will have to ‘raise the bar’ going forward.
