Probability and Statistics


  • You are expected to create three new posts, you only have to post one and save the other two. 

  • You also must find two other sites that are related to yours (write down the sites) post a comment and a link to your website.

  • Your blog entries must have a minimum of 3 categories listed for each.  This allows search engines to find your site.  Go back and edit your entries if necessary.

Asymmetrical Accent Box


This design tends to maximize the amount of paper used, so your volume is much larger than a standard masu or many other containers.  There is a tradeoff in strength.  As my usual disclaimer this design is only 5 steps long.  I asked at the CHAOS meeting if Robert or Joshua were familiar with the design, as Joshua has more origami books than probably the whole group combined.  Neither were familiar so if it is a long standing design post pertinant info.  I think the design looks best with a duo colored paper.  6 inch paper gives you a container that is approximately 2 inches tall and 1 and 3/4 inches on side.

Edit:  Carmen Sprung contacted me and sent pdf’s of a diagram she designed in 2006.   Her design, the KrimsKrams box is diagrammed much better, has a different crease pattern, but a very similar methodology.  On the diagrams I’ve indicated the different places we diverge on the flickr photos

It is always fascinating to see how different people approach things and how similar design development is.  I have e-mailed her back and asked if she has anywhere she wants references and when she does I’ll include it here.

Excellent Holiday Gift-Jeff Rutzky’s Kirigami Book


Jeff’s book would make a great holiday gift.  It is nicely balanced and covers several styles of kirigami.  He has a wide array of designs and artists, which gives a nice sampling.  My favorite bit (although I liked it all) was the pictures of artist’s work.  They give one a level to aspire to, even as we realize that it likely isn’t in our innate constitution.  They sell it at Barnes and Nobles.  Here is the online site.

His website which is a melange of his interests and photographs is here



As I bought Jeff’s book a bit ago I’ve been meaning to try something.  Finally just looking at the pictures inspired me to grab a utility knife(my exacto ran away with the spoon it seems) and sketch something out. I sketched two intertwined growths (in my mind was the folksong “Barbara Allen, specifically the line “They grew and grew up the old churchyard the red rose and the briar.” Well the end result I found endlessly amusing the shadows were a hoot to play with and I was way to visually enthused.
