Friday Puzzles #178

So I'm back from Croatia, dearest reader, and as promised I've made a homage to one of my favourite puzzles from the WPC.  It is a somewhat curious fact that this puzzle type didn't feature in any of the competition rounds, but was instead introduced to me after hours in the bar by my good friends, the merry Polish puzzlers.  Whilst the actual competition is one of the most important thing at these championships, it is my humble opinion that the socialising afterwards with fellow puzzlers is equally as important.  Anyhow, as is always the way with these things, broadly sweeping statements were made by all concerned and before I knew it I was committed to broadcast this wonderful innovation to the world.

Now as I'm sure all my dearest readers now, detuned radio is very much a blog that promotes family fun, but I fear that this week we will be pushing things to the limit.  However I'd like to think that if nothing else, I am a man of my word, so here goes.  Please bear in mind I've had to give a few aspects of this puzzle a slightly different description!

Place some 1x3-cell rectangles of either orientation, and some circles (contained in a single cell) into the grid.  Rectangles may not touch rectangles, and cells containing circles may not touch cells containing circles, even at a single point.  Each rectangle must orthogonally touch 2 circles, to form a T pentomino, and each T pentomino touches a further circle at its base, so that there is a set of several disjoint hexominoes of the same type in the grid.

(N.B. I'm not sure if there is a standard labelling of hexomino types by letters given there are 35 of them, but the one I have in mind is definitely the one that looks most like a capital T.  With apologies to my illustrious e-mail correspondent for the previous ambiguity!)

Numbers outside the grid indicate how many cells in the corresponding row or column are used by rectangles.

If things aren't beginning to become clear, just be thankful this type probably isn't going to feature as a manipulative team round any time soon.  Ahem.  Enjoy!
