I'm not a master, but the most awesome thing that happened recently was partial invisibility during a mirror meditation, where about up to 3/4 of my body dissappeared or faded out momentarily from the visible spectrum in dim lighting. The phase before that also is the body becomes completely black like void or abyss. I don't know if i'll ever be good enough to do it on camera (did some shadowkinesis demos already), but it was an amazing experience.
