Tavin15 (http://www.youtube.com/user/tavin15) tagged me, and challenged me to answer 5 questions:
For instructions on the Alexander Swallowtail Butterfly by Michael LaFosse: Visit http://www.pem.org/sites/origami/ and click on "Fold more models" in the top right corner. Then select "Origami Now!". The butterfly is the 6th model (or 2nd from the right).
But feel free to comment below what your answers are. :)
