I was hanging around a gallery before an exhibition as is my norm - and, on the ground floor there was a pile of rags in an allocated space - well, being fairly art savvy - I looked ----------- and, I looked very closely - and, I was buggered if I could see anything but a pile of rags --
then, I wandered up to the next level and looked down - and the pile of rags magically turned into a woman lying on the floor - perfect dimension from above - but, you couldn't even guess from the ground -(and, yeah -I went down and checked)
