It's a bit like.. if you had a clothes shop and you went to a high profile fashion show where the top designers used top models to display there latest creations. Would you think..i'll have to buy in a load of this stuff to sell in my shop? Think not! Do you think that anyone actually goes out and buys something they've seen on display at a fashion show? Think not! So think of a fashion show as light entertainment and the designers showing what they are capable of. If that inspires you to put your thinking cap on and come up with your own ideas, then it's worth it. If you intend trying to copy their ideas in some way to produce something that will add to your bottom line, forget it!
