also something no one mentioned that might be relevant: the dashes in the morse code are shaded brown, the dots are blue, and the spaces are yellow

yeah, i was looking last night if there were lines of morse through the mosaic based on that, but there's too many long runs (in both directions) of the same colour... but I still think it will be relevant at some point...

My current guess is that we need to whittle down the shapes that are there somehow (remove shapes that match urdu letters or something?) and use what's left as morse code...

i did try it... it's a different WxH ratio, and it in a different scale. If it does overlap, it needs some not insignificant manipulation that makes me think that that's not (directly) the hint

@ArbitraryKangaroo Your idea to reuse the punched card is correct (that's what the phrase is supposed to mean). There are hints in the image how to use it.

@Alconja Did you notice that the small white arrows in the mosaic don't overlap the tiles exactly as well?

I did (it bugged me :P), and figured it was important.

Haven't really had time to play with it properly.. been busy (pretending) to work
