Hey it was just earth hour in NZ. I was sitting outside and had a little smoke. I looked into the sky and then started wondering if I could see HI with open eyes. I started concentrating and I could. I could form circles triangles and squares and also change colours from blue to white and red. It didnt seem any harder than with my eyes closed. I wonder if looking at the night sky makes it easier. But trying to concentrate now it seems just as easy on the wall. It gets harder trying it looking at my desk because there are lots of different colours I think. Anyone else experience this?
