Pineapple surprise

We've been doing things around the house all weekend -- washing towels, cleaning floors with all the stuff Jim and Charlie sent us, putting in sod for the swale (required by the city, so we're ready for Monday's inspection), putting on the pool safety cover (ditto), and on and on.

And late each afternoon I noticed a strobing pineapple on the stairwell wall by the upstairs guest bedroom.

Turns out that when the late-day sun hits a sill in the dining room just right, and the light bounces up through the dining room fan blades, and hits the pineapple cutouts along the loft railing. . . .

You can see it here, but it's even weirder to see it flashing as the blades turn.
