I'm embarrassed to say I needed two hints for this one, too. My first thought was that the lines reminded me of a pair of 3x3 arrays with the middle part missing, so I thought I needed to push 5, the middle key on the keypad, twice. If one just handed me a piece of paper with those squiggles on it and asked me what number was encoded, I wouldn't have thought along the lines of how numbers are arranged on the keypad. On the other hand, I can't guarantee I'd've thought of the correct
The sad part is that I've seen that style of "encoding" (so to speak) before, including here, in the banner below the logo on The Grey Labyrinth
And that wasn't even the first
place I'd seen it.
