Both Eric and Eduardo were asking, how do you make accurate decagons out of a square?
Well, when I’m after accuracy, I draw a decagon in my creaking, ancient CorelDraw 8 install and print it out. But this lacks…authenticity. I’m way big on authenticity.
The method for making a decagon from a square is not difficult and is easily memorized. It is derived, I believe, from an old Japanese method, developed for a folk art called monkiri or crest-cutting. Monkiri involves folding paper in various ways and then cutting out designs in it. When unfolded, the cut paper reveals a surprising image, like an idealized cherry blossom or waves on water. American children do similar things to create snowflakes and paper dolls. The great folder, Bob Neale, once gave me a fascinating kid’s book on monkiri. It’s around here, somewhere.
Of course, once you have trapped the wily and elusive regular decagon, what do you do with it? Well, you could do something simple, like the above waterbomb – you-all know how to make a waterbomb, don’t you? Or, you could get all jiggy with it and make a Puff Star. Kind of up to you, the faithful reader.

Whenever I use Google Language Tools on a Japanese site, I sing this Red Housepainters’ song,
it’s not that simple
this dictionary never has a word
for the way i’m feeling
it’s nothing plain for me
of a different god and moral
what if i laid my head down on your stomach
or put my mouth to your hand
i cannot translate
japanese to english
or english to japanese
Don’t get me wrong – Google provides me with that middle voice feeling, that sense of being on the wrong side of my brain, that I’ve come to expect from trying to put Japanese concepts into the American mind. It’s all good. Check it out:
