This is fascinating. I found it on YouTube this morning by pure chance, as I was looking at this excellent short documentary on the homeless of the city, which focuses on the man you can often find opposite Grafton Street with a chalked message. This was hiding in the related videos.
The project below comes from YouTuber shotak2929 and almost as fascinating as the lifesize model is the way in which Dubliners react to it, often gawking and in some cases interfering with what at first appears to be a real individual. At one point, we see a young lad steal from it. Well done to all involved, the project is certainly thought-provoking.
“This is my end of year project for 1st year in National College of Art and Design, Ireland. The concept of this piece is to let people react to it in their own ways to create the space or the atmosphere between viewer and sculpture.

Come Here To Me! 
no what was freaky fo me there, theres a mad ol wan(actually not that old) with a scarf lookin at it on halpenny bridge, anyone know anythin about her, every day she walks from around Inchicore/kilmainham into town pulling her trolly BUT on the road, Ive seen cars inches away from her. She always freaks me out when i see her. She does the same on way home, walks on the road, only goin on the path when she really needs to. She goes at some pace too
doh just noticed thats actually not her, but does anyone know who im on about.
on the subject of crazy bag ladies , Another mad ol wan i havnt seen in a while, the old woman in the car park in the Coombe hospital, she use to walk around it with an umbrella nearly every evenin. the security guard eventually gave her a fluorescent jacket in case anyone knocked into her. She use to have conversations with herself. often wondered what that poor ladies story was, had she had experiences that brought her back there or somethin.
