Last night, as I was drifting off, it occured to me.
A pattern idea. Using stuff I already know.
Thankfully I keep a notebook by my bed, because my mind finds just as I am drifting off to be the ideal time to insert ideas in my head, which I often forget if I don't write down. This one I wrote down.. but I haven't forgotten.
It's a good idea I think.
I'm looking around at similar patterns and don't see the exact same idea there.. so I think I shall work on it next and if it works out I'll share.
