Some time back, I read a question on the forum where someone wanted to turn one of their super-hero characters to stone. I remember there being a few comments, and at the time, I had no input, but i found a small clip today while browsing that might be of interrest. Unfortunately, I do not remember who posed the question, or when, so I will add the link, and trust that the person scans the forum regularly! :-)
Hope it is of help to someone.
