I call it String Art

Back in the 1960's, hippies used to sell crafts at flea markets. That's when I first saw these simple designs. They would take a piece of wood, drive 2 or 3 rows of small nails into it, and stretch brightly colored string back and forth between the evenly spaced nail heads, creating intriguing designs that had the appearance of curved shapes.

In the early 80's a co-worker had a Color MacIntosh computer with a screen-saver that generated constantly changing line art designs that seemed to bounce off the edges of the screen. He gloated over his superior computing power with it's fancy graphics capabilities. I promptly wrote a program to generate a similar continuously changing String Art pattern on the screen of my DEC VT241 terminal. Over the years, I've utilized several different graphics programs to create String Art designs on different computer platforms; MacPaint, DECW$PAINT, PC Windows Paint, Etc. I now use Adobe Illustrator's blend tool to quickly create any number of String Art designs. Here's an example in 3 easy steps.
1st Line
1. Start with a straight line		 2nd Line
2. Add another straight line at a different angle		 3rd Line
3. Create a series of evenly spaced straight lines blending from the 1st line into the 2nd line
To many people, these designs are reminiscent of the Spiro-Graph toy popular in the 70's. Actually, the Spiro-Graph toy created everything with spinning wheels resulting in circles of looped lines. These String Art designs are created completely with straight lines.

This is the design used in the background of this page. When it's tiled in a background it becomes far more interesting (see the example to the right

It's kind of a trademark with me now. I add little String Art designs to my web page backgrounds or the borders, Power Point presentations at work, in fact most artwork I create will contain some String Art. I like it... Some others do too.
