Friday Puzzles #221

Apparently I was too busy not getting a job in London last week to remember to post a puzzle.  Have no fear, I'll be back with a bang tomorrow!

This week, a quirky Heyawake puzzle, a type I think I haven't revisited for a while.  I was tempted to go wacky on this one to make my original design work, but I think a little perseverance and polish and general puzzling discipline is good for one's authoring abilities.  Under the old system this is certainly hard, but rules is rules and it's not too hard to see where to look to continue your solving path at the sticking points.  Enjoy!
