Picked up some molds today to make the shaped ones. There are 3...a flower, a curved one and a sort of half-clover shape. They were $7.99....and it is usually my policy to not spend money on silly gadgets, but I REALLY wanted them. I got them at Global Giftware, there are 2 sets left I think. (Not that I care....I've already got mine!)
as an aside, the first in this series, "Manners of Japan (Sushi)", is hilarious (esp. if you've visited Japan) for its satiric blend of mistruths & exaggerations delivered in deadpan documentary style:
A coworker of mine's parents own Miga and he just gave me one of these which he could not finish from his lunch. Basically a giant, triangular sushi - it was extremely yummy!
