If you were in my business as an artist my boss would fire you for such inefficiency.<<< And that is why creativity and innovation dies a horrible death at many companies. Instead of firing him, why not commend him for the seed of an idea, pointing out any weaknesses and giving him the time and encouragement to try and streamline and tweak it? It has drawbacks as mentioned here. However, a seed has been planted on a POSSIBLE way to do something that MIGHT allow more creativity and more realism. But we won't know if the seed-planter gets ground into the dirt with the seed. Keep the ideas coming, wolf. Obviously, from what kupa said, it is an idea others see possibilities in. Take care and be well. casamerica
