The ‘treasure’ here is a reference to the idea that ‘x marks the spot’. The ‘x’ in this case is quite intricate.

Today’s Gratitude Item: That my computer ‘blue screened’ (and then restarted itself) while I was in the shower. It tends to blue screen at some point after I use Adobe Creative Cloud and if I’m unlucky, that will be when I’m in the middle of a task which is really frustrating. Happily this time around, the blue screen timing was quite considerate.
