i really liked those hama ironing beads as a kid so when i saw them in a shop some weeks ago i got some and wondered what to do.
since they came in 10 colors like the ten digits of the decimal system i decided to visualize the digits of pi in color.

Step 1: What you need

Picture of what you need
- hama beads in 10 different colors (or ironing beads from any other brand)
- a square or rectangular hama-beads-board, the bigger the better
- clothes iron
- patience
- website or book with digits of pi
- piece of baking paper

Step 2: Assigning the colors

you have to assign the colors and stick with it to the end of the project.

i went with

0 - white
1 - yellow
2 - orange
3 - red
4 - pink
5 - violet
6 - blue
7 - green
8 - brown
9 - black

it doesn't really make a difference which number is assigned to which color. only according to murphys law be sure that the number assigned to your least favourite color will come up more often.....

Step 3: Digits of pi

since most of you probably can't memorize the first 500 digits of pi (i know about 10) go to the internet and find yourself a website that does. for example this one: http://www.pibel.de/

or find a book if you like that better.

Step 4: Get beading!

so all you have to do now is start beading.

3 = red, 1 = yellow, 4 = pink, 1 = yellow, ....

i did the beading from right to left since you turn the whole thing around after ironing. this way when it is finished the end product will show the digits from left to right.

since this will take a while, you might wanna listen to some music on the way.

Step 5: Ironing

put a piece of baking paper between the beads and the iron and iron on medium heat (see instruction on bead-package) until all the beads are fused together.
