Red, white and blew

This is exactly the picture I was trying to capture, timed perfectly with the slip & slider in the background!  I've always had a soft place for pinwheels...I don't know if its their twirly spin or color blur, but their simplicity registers childhood delight every time I exhale one into play. 
Is there a childhood toy in your past that evokes the same
happy-memory fascination?  Do tell!
