It's actually really metaphisical... visual arts deal with light, which in some ways is seen by some as antimatter. Acting is trasferring experiences from others through action, movement, etc... so by copying someone's life you're living their spirit through your body. And when someone writes, they're transfering an idea through time to a different person in a completely different setting. Stephen King was the one to say that writing is clairvoyance. I just put it in a poem in my own words after a moment of relaxation after exams... Haven't puffed for so long... Bout fucking time huh?
