Dogma I can cope with woodchip, though removing it it a pain. But at least it doesn't gather dust like Artex.
Walls shouldn't gather dust. It's wrong.
Do you think it was designed as a subtle a backlash against feminism in the 70s - so there was more dusting for people women to do? 
Mishaps it looks as though the plasterer was trying out very swirl possible, like some sort of student exercise

You can't ever get rid of it then. It's probably a valuable period piece.
conkerpods We had Artex,woodchip AND polystyrene ceiling tiles
I raise you all of the above (though celing tiles in spare room only), AND a gorgeous victorian fireplace destroyed badly painted by an incompetent ape an amateur; there's paintbrsh bristles stuck in it and everything.
Actually the fireplace is a higher priority to sort than the artex... although it's a rented property so not going to do too much. On the other hand, I've lived here several years and basiclly treated it as an opportunity to learn/practise DIY...
