Installation
Download the installer by accessing the direct link
from
http://hexaflexagon.sourceforge.net.
Click on the
icon in the download server corresponding to the location nearest to you.
Save the file HexaflexagonXmasEdition.exe to your hard drive. Locate,
then click on the file name to install the program. Click on
I Agree
and Install as each appears. Locate the file Hexaflexagon Toolkit.exe
in C:/Program Files/Hexaflexagon Tookit, then drag it to your desktop
creating an shortcut for easy access.
Preparing Your Own Images
These instructions require access to the inexpensive
paint program
Ultimate Paint. An evaluation copy of the program
is available for download (30-use
restriction).
When Hexaflexagon Toolkit creates a flexagon, each of
six distinct images is squeezed or stretched until the ratio of the width
to height is roughly 200:173. Then each image is trimmed to the shape of
a regular hexagon
and subdivided into six congruent equilateral triangles. If you use images
with a 200:173 width to height ratio, these will be no image distortion.
To edit/crop your selected images, run Ultimate Paint, then
Open
each image file in turn. Use the information button
to reveal the image dimensions. Click on the Cut Area button
and then on the lower case "b" key to reveal the Cut Panel.
Enter X and Y sizes in the proportion 200:173. [The X size or dimension
should be 1.156 times the Y dimension; the Y dimension should be 0.865
times the X dimension.] The revealed image dimensions should aid your initial
selections. When the cursor is moved over the image, a rectangle with the
selected dimensions will appear. Move your mouse over the image until the
desired area is outlined. Edit the cut area dimensions as needed, always
maintaining the 200:173 proportion. Remember that your rectangular image
will be trimmed to a regular
hexagon by the software. When done, click the left mouse button to
select the desired area. Select Edit, then Copy. Select Edit
again, then Paste as New. The cropped image will appear in a new
window. Select File, then Save As. Save the cropped image
using a unique name. Close all image files. Repeat for each image.
Creating Your
Flexagon
Run Hexaflexagon Toolkit by clicking on its icon. You
should see the beginning of a strip of 36 equilateral triangles in a special
window. This is a Christmas template which you can print for practice and
to which we will refer in the folding directions that follow.
Select Images and then Image1. Locate, select, then Open
your first image. The 6 triangles in the strip of 36 equilateral triangles
that comprise Image1 will be replaced by the 6 triangles that comprise
your first image. You will see the replacement of the first of these triangles
in the special window. If you wish, scroll through the window to examine
the entire strip. Replace each of the other five images in turn.
When your strip of triangles is complete, rotate it by clicking on the
30º button, then increase the resolution of the eventual printout
by clicking on the + button
twice. Select File, then
Export
JPEG. Save your flexagon file to a standard disk (or to your
hard drive) using a convenient name, say hexaflexagon.jpg. If each of your
cropped images does not exceed 800 x 692 pixels, the flexagon file size
will not exceed the capacity of a standard disk.
Printing Your
Flexagon
Run Ultimate Paint. Open your flexagon file. Select
File,
then Print.
Edit your printer Properties. A Tabloid paper size (11
x 17 in) will produce an excellent model. If that paper size is not an
option, then use a Legal (8.5 x 14 in) size. Letter size
(8.5 x 11 in) is too small for easy flexing. Change the orientation to
Landscape.
Select a Normal print quality. Select
OK to close the Properties
window.
In the Ultimate Paint print window, make sure the Keep
Aspect Ratio box is checked, then select Fit to Page under Image
Size. Press the Print button, then await your printout.
Folding Your Flexagon
You may wish to practice folding a flexagon by exporting,
saving, and printing the unedited Xmas template that appears in the special
window when you open Hexaflexagon Toolkit. The instructions
that follow will refer to that printout.
Cut out the printed shape. Fold it in half lengthwise.
You should now have a single-triangle-wide strip printed on both sides.
Align the strip as shown below. The back side of the left-hand end
of the strip should be
GLUE X.
Fold the top two triangles away from you (to the rear), along the broken
line in the figure on the left below. The left-hand end of the strip should
look like the figure on the right below.
Fold the top portion away from you, along the broken line in the figure
on the left below. Again, the left-hand end of the strip should look like
the figure on the right below.
Folding away from you along the broken line in the figure on the left below
should leave you with the figure on the right below. Fold top sections
away from you along the broken lines.
Continue in this manner, folding two triangles at a time, until you once
again have a single strip. The two sides of the strip should look like
the top and bottom rows of the figure below. If you're having trouble,
the folds in this section should all be the same way, a wrapping pattern
rather than a zigzag.
Flip the flexagon so you're looking at the bottom row of the figure above.
Fold the right-hand side away from you along the broken line. Orient the
flexagon so it is in position shown below. Check the bottom right triangle
to ensure it matches the image.
Fold the top section away from you in the usual way. You should now have
a nearly complete picture as shown below on the left. Underneath the lower-left
triangle (it will be the only one that is not from the first image) you
will see the other end of the strip with the second glue tab on it. Lift
it up and over the aforementioned lower-left triangle. The two glue triangles
should be next to each other as shown below on the right.
Fold the left glue tab over and stick it to the other one with rubber cement
or a glue stick. When dry, flex away in the usual way!
