In the film's designs of the wands they are very intricate. I always thought it was over the top and imagined the wands in the books were supposed to look plain and basically all the same, except maybe for the length and wood color\texture. But then it probably could lead to a problem when one can confuse his own wand with someone else's. Which never happens. Actually we see in The Goblet of Fire when Harry loses his wand:
"You were found with a wand in your hand!" - barked Mr.Diggory, brandishing it in front of her. And as the wand caught the green light that was filling the clearing from the skull above, Harry recognized it.
I mean, how different should a wand look so that Harry could recognize it from distance in the dark, in motion and lit only by the dim greenish light?
So I wonder, do all wands in the books have creative designs like they have in the movies?
