I have two fans, one blade-less, one bladed, and my little nephew loves the shit out of the bladed one. Sticking paper into it, taping ribbons to it, yelling into it, watching the blades build up/lose speed, spinning it by hand (I took the safety cover off); he never gets tired of it. The blade-less one... he stuck his hand through a couple times trying to figure it out then never played with again.
