If you have been in class with me you have probably been annoyed by me making origami boxes to hold pencil shavings (so I can sharpen pencils at my desk). You have to have something to do to keep awake when the professor is teaching to the bottom third of the class.
Anyway, This “bowl” design seems like it might be a little more straightforward. I should start precutting origami paper out of old notes and handouts now.
Props to boing boing for this 2003 link!
