Ireland at play

Still trying to come to grips with the instructions for the spontaneous "let's all hold hands around the blip planet" Twigs idea.
I'll get there. Eventually.
A square, that's the thing where all points are equidistant from the top part, roight?
Is midday GMT the same as twelve hundred hour in Grimsby? Is it safe? (I've heard nasty stuff about genetically modified time).
Can blipfoto be held responsible for the damage that may occur during my 5th attempt at taking over my local bar? (the last time I managed to get to the kegs downstairs but I got two broken ribs when Paddy broke a bar stool on my back).
