Cool! I wanna see it built!
On a completely unrelated tangential note about Sumo instead of Samurai:
Was in Daytona one fine spring break having lunch at the Starlite Diner (classic chrome & red "subway car") when I saw an idiot spring breaker (isn't "idiot spring breaker" redundant?), on a boogie board, holding a tow rope, attached to a PU truck's trailer hitch, "skiing" down the (dry) street ... in a SUMO WRESTLER FAT SUIT for "safety".
Naturally, they were INSTANTLY pulled over by the local LEO's! The kid in the Sumo suit got a ride (suit and all), presumably, to the county Greybar Hotel.
A week passes, same bat-time, same bat-place, and the bus from rte 92 (which passes the Greybar) pulls up at the stop across A1A and off pops the kid in the Sumo suit (like, its gotta be the same kid, right?) A week in the Greybar is typical for a Spring Break D&D (Drunk & Disorderly)! Guess he was a good boy!
