The gender idea is interesting, but I have to agree that leaving aside the whole gender politic thing is one of the reasons I play. I mean, if you want 'realism' in that aspect, might as well play Second Life. I like the dandelion idea, and the tree to climb and jump from, they are kinda fun play ideas - but for really special magic I really like the Pegasus idea. It would be really cool to retain the deer form and be able to fly wherever for a minute or two - you know, on VERY special occasions, sort of like a dream or something. Or, maybe when your deer falls asleep perhaps there could be a slim random chance that you would kind of float out of your body, and the player might notice a 'ghost' deer floating over his sleeping deer, and be able to go for a flight for a little while, until just like a real OBE it just kinda ends and he finds himself back at his sleeping form. Perhaps there could be something also in play so the other players could 'sorta' sense the presence of the visiting deer, but it would still be ethereal...
So many possibilities.
