Proposed Gygax monument

As reported in the Janesville Gazette (WI) today, the family of E. Gary Gygax has announced plans for a memorial to Gygax in his hometown of Lake Geneva, Wisconsin, the town where Dungeons & Dragons was founded. (In Fantasy Freaks and Gaming Geeks, I head off to Lake Geneva in search of Gygax and his legacy.)

Apparently, Gygax was into the idea. And who wouldn't be? (and who wouldn't want to be memorialized in this way?). What would the monument look like? Perhaps a statue, perhaps something else. A maze? An animatronic wizards or dragon spewing fireballs? An endlessly rotating d20?

Upon hearing the news, in a spare moment at my local cafe (where much of my book was written), I scribbled down a possible design idea. Thoughts?
