How these things get thought up...

I was doing a bit of painting in the shed a few nights ago and felt the urge to try to doodle this. Pencils took a few hours. Went back the next night and "inked" it, to use the term very loosely, with a ball point pen. Another hour or two. Then dumped it into photoshop and tidied it up a bit, added some colour and some readable text.

I'm still not entirely sure why...
O.o Must be the coffee....
