Ok, time's up, I'm impatient. :) The answer is The Shiny.
For Pirate Bill - it's an image we've posted many a time to represent shinyness. It's pretty intoxicating to look at, for a static image.
I inverted it, rotated, messed around with color, and there ya go.
Good luck searching for threads featuring The Shiny, since we mention "shiny" a lot around here.
ETA - too funny about Walt and the orange groves - this is a postcard illustration from
1910 or so, supposed to be sent to those in colder climates, with a bottom caption (that I removed)
"You may throw snowballs for me, and I will eat oranges for you."
