It really is strange how my mind works. So strange that even after 50 years I still have  no idea what it's doing half the time.
The code on the right I came up with whilst on my lunch break at work yesterday, I was bored and the mind went wandering, when it returned it was carrying that code.

The code on the left I came up with early this morning. I don't sleep well most nights and the mind goes to some dark and scary places.
But somewhere in the dark thoughts was some light. The code.

I remembered seeing something in one of Richard's TechHelp videos. Couldn't remember where, or when.
But i had to try it.
Nailed it first try.
