no one...there has to be a tut i saw one before but i forgot whee it was at ..i think it was wit len flare or something
lens flar + chrome. not sure about bas relief tho i dont use it much. just tinting a chrome'd lens flare would prolly get something similar
did one earlier, basicly make a black background do lens flares, in the number '5' position you get on a dice, now go to filter > sketch > chrome... there you have it.. and then you add all you'r colours in, good luck with whatever you are making too
