Following Wound's suggestion, here is a new term that has given me sense:

"EXprEsSoR": Human being which use a way to interact with life, expressing creations in many differents forms, to be part of the sharing of the whole.
(Do not misconcept this term with "artist", as the nature of this creatures, seems to be attatched to the world in a fairly egocentric way... usw, usw, amen)
