Mystery Macro

This is my entry for the TinyTuesday challenge, thank you once again to  Newcastle Downunder  for hosting.

I've been looking through the entries which are up already, and  there are some fabulous ones;  meanwhile I've spent ages trying to make this look mysterious, but  I'm having to call it a day now and get on with some real work instead.  I'm looking forward to tomorrow and seeing what everything turns out to be.
