Good News!

No, I don't have another model yet. I don't exactly have much time, what with so many things coming to an end and starting up. Hopefully I'll have something else before the end of the month.
First, a few months ago I was e-mailed by Jean Jérome Casalonga asking whether he could include my Man with Bouquet in his upcoming book of Minimal Origami. I, of course, said yes and recently received the finished book, full of minimal origami models with 4 folds or less. It may be a small book, but its packed full of great models and involves plenty of JJ's unique sense of humor. It can be found online on the publisher's website here.

Also, I just received an e-mail saying that the diagrams for my Stegosaurus will be appearing in this years OUSA annual convention booklet, which wont be available for a while. I have to thank Andrew Hudson and Quentin Trollip for reading over my diagrams and pointing out any errors that I missed, and giving me another point of view. Now I just have to keep waiting to find out whether they will be appearing in the 15th Tanteidan Convention booklet.

Again, thank you to everyone that made both of these things possible. Hopefully this will help me to do well enough in my long distance races to make it on to provincials in at least one!

Another Spiky Animal

I'm not really sure how I came up with the idea for this. I guess I was thinking about the different hexpleated model that I had seen, and I started to wonder about octpleating. It turns out that octpleating really is possible, but isn't very practical if too much is used. The CP below is probably as far as you should go, unless you want something like a sea urchin (which are actually folded way too often, I find). After spending quite a lot of time trying to collapse the model, I finally figured it out. The way that it collapses ends up with two legs and a whole bunch of points. I turned the two points in the center into a head, and the rest became spikes. Here is the octpleated CP that I was talking about:
Porcupine CP

It isn't too impressive, but its a pain to collapse. Precreasing isn't too hard if you fold 22.5° radially from each center point. When collapsing, you have to collapse it all at once, slowly. Eventually (with a bit of trial and error), it should fold flat to the size of the center section. Thats the magic of crease patterns.

Spiky Rabbit

Back when I originally folded this, about a month ago, Ubuntu 9.04 had just been released. As always, there is a animal name to go with the new version: Jaunty Jackalope. I'm not sure why, but that made me want to fold one. I couldn't / didn't have the time to fold a full jackalope, so I just folded the head. Anyway, since then I haven't got to refold it and take a picture until this week. I've been busy catching up on homework, working on a one hour presentation about the environment, playing soccer and basketball and training for track & field every day. Its not all over, either. I present my project tomorrow, and the first of three track meets begins the day after that. Here is the CP that I used for the jackalope head:
Jackalope Head CP

It isn't much, so it shouldn't be too hard to collapse. The top section of the CP make the antlers, and the bottom part is the head including ears. The antlers can be color changed, but you have to be careful not to rip the paper. Good luck!
